Could it be possible that mirrors are portals?

I used to look in my bedroom mirror and wish I could climb through it to the other side and escape my life. I always thought it was a better place, but I outgrew it after a few years. There's a book series called Anne of Green Gables where the main character is an orphan girl that makes friends with her reflections because she is lonely, but she outgrows it as well. I think there is something normal about looking into a mirror and seeing something different than your normal life, everything is reversed! Talking to a therapist might be beneficial to you though if it's something that seriously worries you.
