Weird Random Thoughts

 It is a normal experience for me to have weird random thoughts just pop into my head out of seemingly nowhere.  Is this a normal thing?  Does this happen to everyone or am I just different?  I was just holding up my pair of reading glasses and I was looking at the lenses to see if I needed to clean them.  As I was doing this and while my conscious attention was focused on looking for smudges on my glasses, the name Denzel Washington popped into my head.  Why?  I had not, prior to that, heard anything about Denzel Washington nor had I had I been thinking about him for any reason.  This kind of thing happens to me all the time so I normally just dismiss these thoughts and don’t give them any further thought. This time though the thought caught my attention enough that I stopped to wonder about it.  The name Denzel Washington was familiar to me, but I had to look him up because aside from the name being familiar, I had no idea who he was.  This is so typical of things and names that just pop into my head..
