Do you get the feeling somebody is watching you?

I feel like there is a word for this, but I don't remember it at all. Anyway, do you ever get that feeling somebody is watching you even if this isn't the case? (or likely isn't the case)

I definitely do. It's really just recently, but I always seem to look around me when I'm alone because I feel as though there's somebody there...although it's not to the point where I'm constantly paranoid about it or anything, I just sometimes feel like there's somebody there.

Sometimes when I'm the only one home I can hear someone walking when it's really nothing.

Yes, I do sometimes. 

Sometimes, I'll really creep myself out by convincing myself that deceased relatives are watching me >_< ....

^ Same here! I keep thinking my grandfather is right next to my bed standing there staring at me while I'm going to sleep. Yeah I suppose it'd be nice that he's thinking about me to stand there, but it's kinda creepy thinking about that. XD

I occasionally am the one looking at others, not intentionally staring them down mind you, but when I'm standing or sitting doing nothing I'll tend to just look around to move my head and I'll occasionally space out and blank stare at someone. But I myself get the feeling, only when I'm sitting in a room alone or with few people, maybe it's all of my schools cameras that are just shining right upon the students.

Yea, my dad's dog watches me when I get home & follows me around everywhere. Otherwise I don't feel like I'm being watched by anyone really.

The word for this? Hallucinations, I believe.

IDK about being watched, but paranoia of getting killed everyday... Ja.

^ Well, yeah, I guess hallucinations would be the word, but I was thinking imaginary audience or something like that. But I think that's for when you feel that many people are watching you at once. Regardless, paranoia of being killed? Hm, that sounds like it would be terrible. Although I once had something similar just with the thought somebody else could be killed soon.
