Mendela Effect

Many of us — mostly total strangers — remember the exact same events with the exact same details. However, our memories are different from what’s in history books, newspaper archives, and so on.

This isn’t a conspiracy, and we’re not talking about “false memories.” Many of us speculate that parallel realities exist, and we’ve been “sliding” between them without realizing it.

OMG You remember that too that's probably just the mendela effect

The BAM Effect

When you go at least a week without shaving or combing your hair. You dress completely like Shit and look just out right awful. Then just before a big get together or meeting up with a girl you like, BAM!! You clean up real nice. The contrast from before and after makes you seem so much nicer.

John: Dude, you look like shit, You goin to that party lookin like that tonight?
Mike: Nah man, I'm goin for The BAM Effect
