How can you feel when people are looking at you? (If you actually can and it isn't paranoia or something)

Can people sense when people are looking at them, have there being any studies to prove it? If people can how do they do it?

There have been studies, iirc.  Some googling might help.

But, people cannot feel it.

Most oft-cited example is sitting in a classroom and you feel someone looking at you, so you turn around, and someone is looking at you.  Well, it was the act of turning around that caused them to shift their gaze to your movement...
