Flashbakes 

When you start to remember what you did last night when you were extremely high.

Patty: Man, we got so high last night, I can hardly remember anything.

Alicia: Yeah?? I have flashbakes every now and then. We should be able to piece the night together soon.

war flashbacks 

1. When something happens that reminds you of an embarrassing, difficult, or so-disturbing-that-you'll-never-be-able-to-unsee-it event in your life.

2. Actual flashbacks to actual battles. Can happen with PTSD.

Oh my god, that was the same position my parents used when I walked in on them as a kid. I'm having war flashbacks!

Don't you trigger a war flashback, son. I once killed a man!

Flashbacks 

When you've taken hallucinogens in the past and either you're falling asleep or you smoked weed, you start feeling like you're there again.

It's similar to a PTSD flashback
