I forgot to mention...
There were times when the house would be very quiet and I would hear something.
I would get scared as hell thinking that I was hearing things. I used interupt other peoples conversation and say.... "Did you hear that Sound?".
What made me feel better was that I would say things to myself, everytime I herd a funny sound. Things such as...
"That probably was the door"
"That sound was most likely from outside"
You know... things like that.
After playing these mind games with yourself, you would eventually believe them. :)
