I think morbid curiosity is not weird, people rubberneck at car accidents. What you are describing sounds like it is going beyond a passing interest though, and the further you go down that rabbit hole, the weirder it will be.
Since you're asking, it might be a good idea to talk to a professional. You might also consider getting into something like an extreme sport.
I've had a hunch for a long time that people who grew up in a busy household with lots of family around are better equipped to ignore noise / light and be able to fall asleep easily. You should go wake them up and ask them.
It was insane, and pretty enjoyable too
