Here's a bizarre one for you:
When I was 10 my mom used to watch a lot of vintage Nick at Nite shows, so I grew up watching the 50's "Adventures of Superman" TV series. I really had a crush on the actor that played Superman. I used to imagine that he would come visit me at night and bring me presents and tell me he was going to take me away to his Fortress of Solitude and marry me. I was very devastated later when I found that George Reeves (said actor) had committed suicide.
