Mimics

Okay so, I've had this has happened to me several times. It's kinda creepy to me.
So, the other night I was at work BY MYSELF ok my 10 year old was here at home with his dad, and I heard his voice at work loud and clear saying mom it startled me so weird.
The other time I heard one was when I was sleeping I had been at work all night and needed sleep. I was starting to kinda wake up my husband was asleep in the living room and our son was at school, I heard my husband's voice literally talking to me and asking if I was ready to eat yet I said huh so, at that time I'm thinking our son got home and he already Cook dinner so I look up and see nobody. That instantly woke me up so, I get up come to the living room to see my husband waking up so, I said to him baby were you just in the room talking to me he said no I just woke up why so feeling creeped out I said oh ok that was weird he said what I then said oh nothing never mind. Y'all it was so creepy weird. This has happened to me several times before these times, with other people's voices that I knew.
