Orginally it starts with a rocking sensation like you're pulling yourself away from some binding or a straight jacket. Pretty heavy feeling. I literally felt like I was going to fall off the bed in the process. I wasn't sure if I was leaving my body behind. Once free I seem to move rapidly. Getting back was a lot simpler. Blink of an eye along with the thought of returning and I'm back
Last couple of times were somewhat different. Since I used the Nova dreamer. Once I woke up and thought hey I'm lucid dreaming and then realised that that it woke me. But noticed that my body was sound asleep so I figured alright now I'll have a lucid dream what will I dream about?
Now this gets weird. I start pulling out of my body. I wind up saying in my mind... hey whoa I said lucid dream Not OBE.. This is the odd part, I never heard of it happening before, but I felt like I was half in and half out of my body. The part of me that was partly outside my body waited... then I said OK OBE then and I was off. Nothing like the rocking sensation I had before. I don't look for OOBEs since I tried learning it 8 years ago. Thought it was too much to bother with so let it go. Even though I was successful without much effort and within 2 weeks of reading the book on the subject. There was too much going on in my life at the time that Astral traveling was just an interest.
I must say though they are easier to achieve alongside lucid dreams. I've had it happen toward the end of a lucid dream too. I'll see if I can track down which book it was that first helped me experience OBE's.
