So last night I woke up from a dream and didn't move, deciding to try to DEILD. I felt my body start to vibrate and heard a loud humming noise, but then I kind of freaked out because I thought "what if I go into SP, but then don't go into a lucid or fall asleep". What made it worse was that I was in an awkward and uncomfortable position, so I didn't want to be stuck like that for a long time. Then my alarm for school went off so I had to get up anyway, but in the future should I worry about this? If you go into SP then don't fall asleep, how long does it last for?
