Sure! I find dreams and nightmares fascinating, I tend to have observation dreams all of the time, feels like I'm watching a movie and they always tend to be disturbing (but very interesting).
I'm also inspired by games that make you feel uncomfortable, such as Harvester, Phantasmagoria, Bad Mojo, I Have No Mouth and I Must Scream etc. all point and clicks I would recommend to anyone who likes disturbing games.
