Saw someone in sleep paralysis?

I think this is sleep paralysis,but it usually happens when I'm awake lying down.I still see everything around me & I am also very aware of whats going on,I still think,but my body, is completley paralized & I am also unable to speak, or even make a noise.I start panicking, then it will go away,& I feel dizzy. It always feels like someone is in the room with me.

This morning I was watching tv, & felt the paralized state come over me except I was no longer looking at the tv I was looking through the doorway into the hallway.All of a sudden my brother appeared in the hallway and I screamed.I screamed because I knew he was still sleeping in his bed,& he really wasn't in the hallway....& I could see him in the mirror out of the corner of my eye, but the thing is you cant see whats out in the hallway in that mirror because of how it's placed. After it ended, I got up, and went into my brothers room, and to this moment, he is still fast alseep.
What is that...called?
thanks<3

It could just be nerves but you really could have a spirit and it could be taking the shape of your family members. Go online and look up the TAPS number or if you have dish tv the watch channel 122 and look for the show ghost hunters

Really creepy

you need to go and see your doctor and tel him everything u just said in fact print this off and show them as its easier for them), it seems like u are showin signs of hullucination, do you get enough sleep (8 hours a night for most), have u had a tramatic experience?

you shud go see ur doctor, they can tell you what's wrong and maybe even refer you and to rule out anythin serious.
