low creativity?

p.s. : Sometimes I think I have more lucid, creative thoughts when I'm low. Like I think of all these random interesting ideas, or even can synthesize thoughts better than usual. When I was walking home and low (sometime between the 72 and the 55), I had a few ideas about some stuff I've been stewing over and trying to write about all week. This is when I'm just starting to get low I guess, before I get too cranky, although sometimes I thin it happens even when other forms of coordination/strength are starting to go. Anyone else noticed something like this?

Maybe it's like being high or something, an altered brain state gives you a new creative perspective? Lowered inhibitions to think more freely (especially about stuff I'm trying to write and therefore may have anxiety around)? Or maybe it's just the adrenaline rush.
