Hello, so I have a real concern regarding needle prick. When I was sleeping one day I woke up and went to the bathroom, and noticed there was a needle( sewing needle) on the counter in the bathroom and it looked as if there was dark stuff on the tip, could have been blood I thought. Anyways I live with this guy who sleep walks a lot. Ive noticed a couple nights I would wake up and find him in my room just standing in the dark which had me worried. MY question is, do you think I would wake up if I got poked by a sewing needle in my sleep? and I don't know if the guy has hiv, but just assuming he does, would it be possible for me to sleep through being poked and possibly getting hiv from the sewing needle? Am I at risk? Do I need a test? please help!
