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

Babe, I was falling asleep after a bowl and I started.. remembering a trip, I think I'm having flashbacks

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!
