For reference I had been meditating regularly and practicing the LBRP and lesser hexagram ritual daily if not multiple times per day at this point in time.
One day at home I became extremely sleepy while chilling at my desk in the middle of the day. I followed a trail of pepto-bismol fragments from the floor through the hallway and into my room, where they lead to my bed. I got in and began falling asleep, and at this point is where the strange experience began.
I felt myself floating in place, as if there was no bed beneath me and my body did not exist, or was as light as air. My sense of orientation and size was completely gone, and it was like I was in a void. I began to concentrate on my third eye, and create a pentagram over it as I normally do, and it appeared glowing green with eight rays of red lightning spinning around it, progressively intensifying with this really loud, bright, trembling. At a certain point I felt like I was moving at an incredible speed, as if I had shot through a wormhole, and I was seeing fractal patterns very vividly as some people describe during a DMT breakthrough experience.
When I exited the portal, I was in this place... a pretty normal Earth-like room of sorts with other seemingly human people, except we were all naked. One woman sitting on a pew across this room from me looked nervous, and i noticed I was also naked. Some man (clothed) with gray hair passed out books to us and I struggled to make out the drawings in this book. Within moments I very consciously faded and awoke eyes open on my bed.
Has anyone ever experienced anything like this? Could it just have been a dream?
