I'm afraid of the oven when it makes any kind of noise or smell, the washing machine when it bangs or shakes, and cars when they hum. I don't know why! Answers?

One possibility is that you are letting your imagination get away from you... This can happen to creative people who are under stimulated. If you don't have challenges for your mind to solve or creative endeavours to release all that 'personification of inanimate objects' stuff, then spooky stuff can begin to happen.

Alternatively, you may have suffered some sort of trauma in your past - and these household items are triggering memories you are trying to suppress.

Also - if accompanied by other symptoms, it is possible that you are suffering from some sort of anxiety attack or health issue.
