Poltergeist messed me up for real! I was way too young, thought it’d be just some ghostly fun— but nah,. That clown scene alone had me checking under my bed for years, and don’t even get me started on that creepy TV static. I legit couldn’t sleep right for days. That movie had me regretting every second, but I couldn’t look away!
Friday the 13th in 3D. Saw it in the theater when I was apparently 12, with a whole junior high friend group IIRC. Don’t know what we or our parents were thinking, sure left an impression and a couple of night’s worth of bad dreams. The 3D effects were effective and pretty nasty.
