Hello to everyone,
I want to start off by first thanking you Jhanananda for allowing me to post here.
I am 21 years old and I have been meditating on and off since early summer of 2011. I started off meditating sporadically about 20-30 minutes once and sometimes two times a day but only about 4 or 5 days out of the week. But by August 2012, I had found a few online gurus who insisted on meditating at least a few hours everyday. I was desperate and I had not tried meditating that much and decided (against the advice of the neo-advaitans) to try it out, just in case 2012 just so happened to be the end. I found pushing into the hour mark gave my mind and body time to settle and truely begin to relax. The pose I have used almost every time has been lying flat on my back with a small pillow behind my head. Sometimes I sit on a pillow or bed to work on sitting meditation, but I'm still working through a lot of tension and trauma I caused to my body playing sports in my teenage years. But since starting meditation I have become aware of a lot of pain in my body. I had surgery earlier this year, and since then it has been like my body has been under constant reconstruction. I had not realized how bad my posture had been and how injuries had altered the way my bones and muscles carried my weight. So stretching has been my bodies savior as well as mediation by helping me become aware of and relax those tensions.
I started to enjoy meditation so much because I found a lot of relief from both my physical and mental issues. But shortly after November 2012, I began to find fears coming up. There were just simple things like my fear of heights that was challenged first by the floating sensation I would feeling in meditation. Sometimes it would just feel like I was high up and I would feel nervous. Or a full body warmth that felt like I was being lightly baked in the sun or a fever (couldn't help but think maybe it was the devil or a demon). By this point I was meditating at 1-1.5 hour intervals about 3-6 times a day. Then within the following weeks I found that a lot of fear was coming up due to the sensations I began to feel. Piercing and expanding sensations in my head, throat, and heart throughout the day. A tickling at the top of my head like ants on my brain, and a sort of sensation like I am about to float out of that tickley sensation at the top of my head (feels weird trying to explain that feeling). The sensations grew more and more until around February when they were so intense, that I could not sit still without some kind of distraction. I felt like I was being wiped out by the sensations and was really afraid of possession.
My vision field was beginning to get a high definition quality to it and sometimes it felt as though there was just too much for me to see. The same happened to my hearing in that it felt as though no noise in the vicinity went past without me hearing it. There were a couple of days I just laid down in great fear because I couldn't shut anything off and distract myself. Sleep was my only comfort, what little I could get. At just random intervals I would just get waves of energy in my body and the various sensations would get stronger at the same time. Throughout the day, it was usually intense enough to feel like I was going to lose track of myself physically or mentally. I also began to have dark blue almost opaque orbs and sometimes a very quick static flash in my vision field(I am not certain if these are charismatic). I thought I was going blind and went to get my eyes checked out and was told they were fine regardless of those symptoms. As for the tinnitus I have, I can not tell you the origination of it. I remember hearing it in silence when I was young and about to take a nap or sleep, so maybe I was born with it if that even happens? So I can't say that it is charismatic either, it has never changed to another sound, it sounds like I'm hearing it in both ears, and I hear it with earplugs and no external disturbances. It does get louder sometimes on its own, and seems to become more noticable when I meditate consistantly, but that could just be me being more aware of it. It kept me from sleeping when I first began to notice it was always there earlier this year, but I've been feeling a little easier about it lately.
I stopped meditating from April till June out of fear, and the orbs disappeared from my vision, as well as the floating out of my head kind of feeling which gave me a more grounded feeling. But when the sensations in the chakras and light waves of energy throughout the day started to slow down, I found myself being agitated by life again and missed the kind of cushion the sensations felt like to the harshness of the world. So I began meditating for an hour in the morning and at night, and sometimes during the day, and they turned up in intensity according the time I spent in meditation. No visual stuff now, but intense body sensations that sometimes feels like a palpable big fat grub wiggling in my chest and head, it is oddly pleasant but still intense at times. I also had come across the GWV around July and that helped me to feel like maybe these things aren't pathalogical or made up.
As for what actually happens in meditation, I usually begin by lying down and relaxing my body. I follow my breath if I need to, but recently I just sink into the energy or feel for the piercing or tingling in my heart. After my mind and body settle a bit(which definitely varies in time every session), the sensations get stronger and eventually I start to be mainly aware of the energy sensations and my body falls into a secondary awareness. Most sessions have ended up with me A)falling asleep B)going unconcious or into black (cant tell which one) C) what I think might be lucid dreaming or D) Just enjoying the sensations arise and intensify and then ease after about an hour and a half. I have not had any activity in my spine or a jolt up the back.
Also at night, especially the nights I meditate right as I'm falling asleep, I find I have what I think are lucid dreams all night if not just nothing. I feel aware in the dreams, but not like "I am dreaming". The reason I don't know is because I still go through with reactions as if everything is normal in the dream. Like if I'm all of a sudden in someones car going somewhere, I don't question it, its as if I just woke up in the next situation and go along with it. The other night I was some random prisoner on a bus, and a few guys decided to escape and I was appearantly supposed to be going with them. I didn't question like I would here and rationalize that I probably wouldnt get away with it, or even that I was a prisoner randomly, instead I ran with them immediately like I was meant to. Is this lucid or just a regular dream? When does a lucid dream cross the line into an OOBE?
I realize now that this isn't necessarily an introduction, but I am working on it. I will get a more proper introduction down when I get the time to do so, but for now hello and thank you for reading.

I apologize for the length and if it doesn't make sense in some areas. Please give me any guidance as to what's what in this description so for, and please let me know if I need to make corrections in my practice. I have read many of your writings and book, and watched many of your videos, but this is the closest I can get to actually talking to you about these things.
