Oh, The Freakishness Never Ends UPDATED/ Pictures

I get into my game today and all seems well. At first with how much the loading music played, I thought it was going to continue once the lot loaded. Had that problem, recently. Thankfully, no, and all is going along as it should. With the exception that I get a male Sims' voice rather audibly on that lot. Just now he sounded rather sinister in the way he laughed. I have gone from top to bottom of the four-stories and can't find a Sim out-of-place. True enough when my singer Sim goes to have his photoshoot, which is a rabbit hole, I can generally hear the clacking of the camera shutters. Once in awhile, when he's in studio working on an album, I can hear his voice saying something or other and sometimes, he sounds pleased with whatever it is. But, this voice is a tad different. Like I said, it's a deeper voice and he laughed in a manner of one preparing a notorious scheme. I did see the Doppelganger of a Stan on the lot early on and I heard a voice at that time, too. I did think it was him, but then when I zoomed in on him, he didn't appear at all to be speaking. And, so far, I can't find him on the lot. I've gone from floor to floor, thinking he got access inside. Can't find him.

Has anyone else had such an occurrence in their game? A bodiless Sim voice? I swear, I'm not going crazy. LOL
