What happened was as following:
I went to sleep in my bed.
I wake up in my living room on a mattress. I stand up on the mattress, completely awake, knowing I am moving my physical body, yet also knowing I am in my bed.
This was not any kind of OOBE/Lucid dream environment. I had many lucid dreams .
This felt simply and exactly as if I was completely awake physically while my eyes were giving me wrong information !!
How crazy does it get ?!
So Im standing on the mattress and I know Im seeing fake. I feel with my hands as I move very slowly and in what appears to be thin air, I hit the wall with my hands, knowing exactly which wall it is in my room. I didn't know what to do and so , dazzled and confused, I returned to the mattress and fell back asleep , waking up in my own bedroom..
That's probably the experience that had the strongest impact on me.
I've had lots of lucid dreams as a child and nowadays as well and a nice number of OOBE's as well. But almost all of these experiences have been forgotten shortly after they occurred.
This experience, despite the years that passed since that day, is still very fresh in my mind.
