Curious if the excessive daydreaming can be hereditary or could a person be predisposed because of genetics? I think my mother also lived in a fantasy world. She spend quite a bit of time alone, she was a homemaker and never worked outside the home. My dad was retired from the Navy and up until I was about 10 he was gone most of the time. She did have emotionally and physically traumatic experiences in her younger life that I think may have cause her to retreat into her perfect world.
