I have this mental condition

Yea yea.. so what.. I have lots of em... but this one is kinda odd, even to me. Let me try to explain.
When I walk down the street, my head facing forward, I notice things in my peripheral vision. .Things like the edge of a tree and my brain go's boop when I get to it, and then boop when I pass the other side of that tree.
It might be the bumper on a car, or the car windshield, or the seam on the car door, or maybe a garbage can, or a crack in the road.
I don't turn to look at it, I just notice it, and as I walk my brain is always watching on either side.. boop booping as I go.
Does anyone else do this? I have never seen it mentioned anywhere.
