yeah i feel that every day.
i am working on something with my head down,
then i get this tingleing sensation on my back, and my brain just goes "whoa! is someone watching me?"
and i turn around, and yep yep some1 is!
i wonder why we feel ppl eyes staring at us when our backs are turned. the expression "eyes on the back of your head" comes to mind.
Yes, this is what I am referring to. When you have your head down, or you are looking straight ahead... and think you are totally alone... you don't even know anyone else is present... but you are suddenly distracted by a "feeling" that comes over you... a feeling that you are being watched... so you turn your head... and you are shocked to see that, indeed, someone else is present, looking at you.
Or here's another scenario: You are seated in an audience. Suddenly your attention is diverted from the speaker on stage. For the purpose of this example, let's say the speaker on stage is at the 12:00 position. You feel something like a "tug" or a tap on your shoulder. You turn around and look over your shoulder. All eyes in the audience are on the speaker. However, behind you, totally out of your peripheral vision, at, say, the 5:00 position, is an old friend who has spotted you, and has been looking at you. What made you "feel" the old friend's eyes on you? What pulled your attention away from the speaker, and made you turn around to took?
Yes, sometimes it's as if I have eyes in the back of my head. I can't say it happens to me every day. But it's happened to me numerous times in my life.
