I dreamed of a giant school invaded by cockroaches and distorted reality

I was in my school, but it was like 5 times bigger. besides that everything was normal until there was an invasion of cockroaches. they don't scare me so I joined the teachers to kill them, while trying to protect myself from them. after a while I went to the class, but the french teacher was teaching biology and everything felt weird and kind of creepy. I looked at my watch and it was completely distorted. when I look up again the whole world and people are distorted looking at me while they become more and more creepy and distorted. that scares me a lot and I try to escape but the world becomes so distorted and creepy that I can't and wake up finally
