I have been looking for a community to open up to regarding my personal experiences with OBE's. I'd first like to give a little history about myself.
I have had insomnia since the age of 12 (chronic). I have had sleep studies done and doctors were never able to really determine why I cannot sleep correctly. I have been on medication on and off since that age. My first experiences did not occur until I was around 16 years old. I am 22 now.
My first few experiences scared me entirely. They were extremely vivid and I could only travel as far as my memory had served me. For example, I could only go down the street as far as my memory recalled each detail of trees, houses, etc. I could remember seeing the dew off of leaves and remembering how realistic it felt. The only way I have ever been able to have these experiences is when I lay on my back trying to fall asleep. I never am able to sleep on my back so that is why I believe they occur. I have induced them by laying on my back when trying to project.
It is also important to note I believe that I started having hypnogogic hallucinations around the age of 16 as well. Some of my dream-elements would be portrayed on my walls when I would wake up. I would actually get up out of my bed and chase after these to confirm if it was real or not. They first occurred when I was on Ambien. Ambien stopped working in terms of helping with my sleep and the OBE's subsided for a few years. Within the past few years I began having them again and tried learning from them each time. I have more recently began looking back at my body while I project.
I can best describe my experiences occurring without any sense of vibrations as other people note. I feel a slight "shift" between my physical body and I often look down at my lower torso when they begin to occur and see a transparent copy of myself raising from my physical body. I have also seen through my eyelids a few times to a fixed object (such as a clock) when they occur. I also feel a slight sensation when I want to return to my body. I noticed they often occur when I am slowing down my breathing as well when laying on my back. I often wake up 5-6 times a night and get a drink so I feel that is also part of the reason i am subjected to them.
I do not have extremely vivid ones like I did back when I was 16. I think that they are happening more naturally now, as I do not take very much in terms of medication to sleep. They always occur now after I have had a full nights rest and when I am tossing in/out of sleep between 10am-noon.
I believe I have encountered some kind of spirit before above my house that have stopped me from projecting further. I am not really sure how to explain the presence. Although the presence for some reason resembles a female. I also began writing some of my more recent experiences on paper after they happen. I have also had a few experiences where it has felt like I was just getting "Sucked" up into the sky without any control. Out of fear I returned to my body and awakened.
I am kind of curious with my history, what methods anyone could suggest for trying to induce these before I go to sleep or during mid-day. I have heard of meditation techniques to induce these but I am not exactly sure which direction to go. I was wondering based on my explanation here if anyone could point me in the right direction. Like I said, I have never experienced these "vibrations", it has just always felt like a "shift" between one body and another. I am usually flying when these occur and not walking. As I have said earlier, as of recently I have been able to gain some control and turn around to look at my physical body laying back in bed. I have not however, been able to get complete control over destinations where I travel. I would say that I may have 1-2 projections every two weeks, although they can be very short, and most of them occur without intent.
Thank you

Here is an example of one of my more recent experiences...
About a month ago my cat of 15 years old died. Her name was Bootsy and she was a great cat. She was inbred and was a bit on the crazy side. After she died and returned home we I had to go buy a plastic container to bury her in outside in our Yard. We had always intended to bury our cats once they died in a place outside near our garage. Our other cat is still living. After she died a few nights later I had a OBE that I did not induce. The first thing I wanted to do was visit bootsy's grave. My body shifted upwards and to the left. I began making my way through our hallway of our house and into the living room. The atmosphere during this particular experience was not very vivid. It was a very monochrome experience until I went outside. I went through the wall of our living room and outside. I saw our green grass and the hill that led to our garage. I ventured to the back of the garage and saw bootsy's grave site. It was marked with a rock and flowers in which we laid down when she died. The interesting thing about this entire OBE was the fact that when I reached my cat's grave site it was illuminated entirely in purple. I could not even see the rock, all I could see was a bright purple cloud. I researched this thoroughly and came to the conclusion that the color purple represented "mourning" in terms of Christianity. I quickly returned to my body and forced myself awake after being content with my experience.
