Alright so i will start out asking if anybody when they are really drunk or high feel the onset of SP when you are somewhat getting close to going to sleep?

My story is last night i was really drunk and high and i felt these vibrations right before i laid down. Then i actually laid down and just shut my eyes for maybe 4 secs at the most and all of a sudden i see these vertical lines so i start starring at them then they start moving really fast and i just see houndreds of shapes and lines.....it was honestly amazing. Then after as it started it was over. I opened my eyes to find myself in SP. Has anyone else had luckw ith WILD while drunk or high? How often do people see the shapes and lines i saw? And last why did i feel teh onset of SP before i even laid down?
