What do you call the single frames popping up? (SH3)

I'm playing Silent Hill 3 and one of the things adding to the feelings of paranoia and panic are the single frames popping up, can't much tell what they are but they are pretty freaky. If anybody doesn't know what I'm talking about it's just like in the movie Fight Club lol.

Just wondering if there was a name for it so I could googl'it.

with the arms reaching out for you? Wasn't that one of the boss fights in that game too?

Subliminal messages? Jumpscares?

hey bud howz it goin mate.

Not bad man, you? Excited for FarCry 4?

Yeah I'm ready for far cry 4 it looks nice doesn't it and you can tell by some of the gameplay videos that the graphics have been improved.

Yeah, it looks like more of the same but with a darker tone, which is perfectly fine since FC3 was almost perfect. They only need to make the game more difficult (FC3 was a bit on the easy side) and we're golden.
