This is the E.T. ride at Universal Studios that frightened Elliot. You can see how someone who is sensitive to sensory input could feel overwhelmed:
“I had a miserable time on this ride, however, because the dark atmosphere and the mechanically moving alien statues that lined the queuing area scared the hell out of me. By the time we got to the actual ride, I was crying in fright.” (from My Twisted World)
