Is it normal for things you're already familiar with to seem new sometimes?
An example: I've had long hair for a couple of years and just recently cut it off a couple of months ago. Sometimes I'll look in the mirror and be kinda shocked like, "Oh wow, my hair is short.", even though it's been short for several months now.
Another example is, I was recently watching a video on youtube of this band, and I noticed the drummer. When I looked at the drums there was this kind of feeling, like "oh I forgot drums existed... weird". Does that happen to anyone else?
