The War of The Worlds soundtrack scares the hell out of me. The Red Weed from that was used during my music exam in High School and I came close to having a panic attack as it had such an effect upon me.
Likewise I had no idea that Forever Autumn was used in WOTW but the first time I heard it, it really spooked me.
Another song that makes me feel strange is Mmm Mmm Mmm Mmm by Crash Test Dummies. I don't know why but there's something sinister about it.
Does anyone else experience this effect with certain songs?
