Put in headphones to listen to music. Phone screen still black,

On old switchboard systems? Yes. Not cellphones.

Not fucking related at all, but it reminds me of when I was on the phone to my gf at the time, and I could hear shit, people were talking, so I told my gf to shut up and listen and then we could both here these other people talking.. Then later they said shut up and listen, and they listened to us. Not paranormal but was funny at the time.

When I was at University my speakers used to start emitting weird noises and talking in a strange language. They used to do this in the middle of the night and would do so even when they weren't connected to anything.

Used to freak me the fuck out.

I later found out that it was portuguese shipping forecasts which were being picked up. Your phone is probably doing the same thing.

I would occasionally hear voices coming from the fax machine at my previous job.

Yeah, that used to happen to me as a kid, when I was on with my best friend.
