What is that movie you saw at too young an age that still haunts you to this day?

The Omen at seven. I wasn't allowed to watch the "scary parts" so I only heard them. Turns out the audio design was way better than my parents gave them credit for. The sounds of the dog attack, falling shingles, and zombie nanny were burned into my brain for years.

Then I watched the movie properly as an adult and... it kind of sucked. The reality couldn't compare to what my imagination conjured up from the sounds alone.
