My dad had me so convinced that I was actually driving the boats at Disneyland (they're on tracks, of course), that I later had nightmares of crashing them.
To make matters worse, I confused one of those nightmares as being a real memory and thought that I really had crashed one. (It wasn't until I was a teenager that I realized I was wrong).
