I don't think it has anything to do with anyone else as these obsessions have nothing in common like that. It wasn't so much that I watched Thunderbirds with my dad, he was just watching it, it was on, I took an interest in it and became obsessed.

The self image idea might make more sense, the only thing these obsessions have in common is my feelings around them. They are intense and go far beyond normal interest/obsession. And these negative daydreams, I just can't figure them out.

I understand the positive ones, it's just me fantasising about having something I can't have. That makes perfect sense. But to have the objects in the daydreams and abuse them seems to be going in the opposite direction? Why would I enjoy something negative, I don't understand.
