Do you have intrusive thoughts?

[oprahwindfury]

Intrusive thoughts as defined by Wikipedia are "unwelcome involuntary thoughts, images, or unpleasant ideas that may become obsessions, are upsetting or distressing, and can be difficult to manage or eliminate."

I regularly get intrusive thoughts. Sometimes I will be driving on the highway and my brain will tell me "I wonder what would happen if I jerked the steering wheel while going 75 mph (1.60 kph for the non-Americans). Or I will be cooking one day holding a sharp knife and all of a sudden my brain tells me "What would happen if I stabbed my leg? Would there be a lot of blood? Go on, do it."

No I am not a diagnosed schizophrenic. I'm told by my psych teachers that this is common and normal occurrence in people.
