For at least 4 to 6 months, I've been having this strange thing happening. I hear what sound like singing, talking, or conversation taking place somewhere outside the room I'm in. I sometimes go to another room to see what it is, find nothing, return to what I was doing, and I keep hearing it. It is usually something that sounds like singing, but it can also be some type mechanical type sound. I frequently go around and turn off anything that might be producing sound, and it stops. I usually can determine the exact source of the sound, but the sound is not the sound that I'm hearing, even though the sound I'm hearing stops when I turn the item off. It isn't bothersome or scary or anything, not threatening. I'm not hearing voices telling me to do anything. It isn't inside my head, but I'm actually hearing something that is making a sound, only I'm hearing a totally different sound...like someone singing a song with words when the sound is actually coming from the heating system or something. I've never had this before. It doesn't happen every day, but mostly every day, and sometime numerous time throughout the day. It is really weird. Is there any way this might be related to Alz, or is just something I should ignore and forget about. Just wondering. And by the way I'm not going crazy and I'm not stressed out when this happens and it is not upsetting. But it is odd enough that it gets my attention right away. Thanks. Oh, this isn't tinnitus or anything like that. I also sometimes think I see things out of the side of my vision that turn out not to be there, but I don't think that is much of a deal. Thanks.
