What that means is I have no idea if dreams mean anything

Well sience says that a dream starts as an idea and builds on that and a nightmare is simply two ideas clashing and combine it to something bad

Same here in fact I slept 10 hours and still woke up feeling like crap

I do it to and not only cracks but grinds like a cement mixer literaly like some people I know get pissed when I do it becuse they can hear it
