This could sound really "woo woo" (borrowed from another thread) but I just wonder if someone else knows this too.

I can be in my "space" doing something and I can feel when someone comes into my space. It's not like I see them, I "feel" them there. I don't know how to describe it, but it's almost like a vibration maybe. Maybe like a "knowing" ?

I want to delete this, but I'm really curious if anyone else feels/experiences this.

It's like an alert feeling, if that makes sense.
