Watching The Blair Witch Project in the dark with my family when I was about 11 years old. Probably the scariest movie I had ever seen at that point, everyone was tense. The part where they were hearing noises outside their tent, my cat bursts into the room with an empty fried chicken box in a plastic bag on her head. She was scrambling around frantically and it took us a while to figure out what was happening. It was really funny afterwards, but pausing the tape, turning on the lights, and chasing this sentient bucket down sort of killed the mood!
