Is it normal for my mind to wander off this much?
It's usually whenever I'm reading something or in a conversation. I try to pay attention to every word but all of a sudden a certain idea or phrase reminds me of something or makes a scenario in my head that makes me forget my present state and focus on the thought.
For example, the other day a friend was telling me how her aunt just converted to christianity. Then suddenly the phrase "holy ghost" pops into my head, and then I remembered how much I'm uncomfortable with the topic of ghosts. Then I imagined how cool it might be to be a ghost without all the grief and misery and just travel where I want to. Then this whole cinematic scene forms in my head with my transparent body soaring through the night sky looking down on a glowing city.
When she noticed the conversation went to a pause she kinda snapped me out of it. I was embarrassed when I couldn't recall much of what she said after my focus started to fade. I'm sure if she hadn't called me back to earth I would have just been standing there for another 10 minutes getting to know my ghost girlfriend who I crashed into flying through an old night club. It's always occurred since childhood and by now I thought I'd grown out of it but I'm 16 and having a hard time dealing with friends and school because of it. My parents don't seem to understand either.
I'd like to know whether or not this is normal. Any advice would be highly appreciated.
