Very interesting to know this is a real phenomenon.

On some occasions, a word someone said sticks, and when I keep thinking about that word, it starts to sound strange, weird and a silly made up stupid sounding word. I noticed that it happens with any word that I pick, not just the words that get stuck.

I use to think to myself that it's interesting that a word becomes stupid the more you think about it. Now I know this situation has a name. Thanks.

Hmm. It would make a lot more sense to me if it were called semantic saturation, not satiation.
