room after blue room, i tripped on LSD...

a few nights ago, i talked with my friend and together we worked on some cosmic problem over the phone. after that, i felt physically weak. the next day, i took a nap for a few hours (barely slept the night before), and in my dream, i was walking in school to a new class.
a big sign said "room 2-0-something" with a big black arrow.theres a board leaning against the wall, and a rectangle slit is the opening. i scoot in sideways and realize i'm in the teacher's office "which was, for some reason, forbidden to students). anyways, i turn around, and see nothing but light blue wall. i crawl through more rectangle opening and through tall mirrors, and go through about 3 or 4 light blue rooms.
the whole time i'm panicking because i know i'm just getting deeper and deeper into something i don't want to get into, and the whole time, this dark booming voice keeps going "LSD....acid trips are so fun....you're tripping, girl! get out of it! have fun with it!"
then i woke up.
???

any ideas on what this could mean?
and PS- NEVER took acid.
unfortunately.
