I didn't know how to really word the title but here's my example, hopefully you'll understand what I mean.
One night I had a really bad toothache and couldn't sleep. I decided to watch The Road to El Dorado instead to take my mind off it. Now whenever I rewatch or think about the film, I am reminded of that time I had a horrible toothache.

Or another example, I asked my cousin this same question and he told me he knew what I meant, he tried watching 10,000 BC while he was really ill and now he can't watch the film again because it makes him think of that time he was ill.

Dune reminds me of comfortable childhood times.

Star Trek The Motion Picture always gives me nostalgia
