I wake up at like 1pm, go back to sleep, and then like I have these really vivid, intresting, really weird dreams, I can't even explain it but I thought up a good idea for some sort of gigantic boat/water park

I recall them well, and can recall 1-2 dreams per night, but I can't believe I don't notice they arn't real when I am say, drinking coke from a bottle thats just $100 bills printed instead of the regular coke thing, or when I'm on some sort of american idle and I out-rap like, snoop lol (i hate rap )

Then theres the fear and loathing dreams where I do like 30 different drugs and I wake up and I stay high for like a couple minutes, thats so weird is that like placebo or is my brain actually releasing endorphines because it thinks Im smoking grass, or droppin acid?
