…OK I have a serious question…have you checked in your house…is there been any leaks in the plumbing where it may have wetted the sheet rock on the walls and made it damp for long period?
If you have allergies/asthma…then the dampness causes Mold to grow…which is very bad for health especially black mold…check it out on the web for yourself
or you could have sleep apnia…lack of sleep can make you hear voices too…have a doctor check your sleep patterns.
hope you feel better.
