Idle diesel/gas generator with accompanied low pitch sound. Very annoying and makes me uneasy. Sometimes I have the feeling that I am in a coma and it is some backup generator in the "real" world Please help. as much as I am in control of myself, this sound is getting pretty heavy on me. I wish I could sleep normally and to not to have to force myself into various sounds to fall asleep.
