I often wonder what it would be like to be another species
That's very interesting. What species you think you would like to be?
I want to be a dolphin for one day
t's normal for the mind to wander and wonder about odd things, and as long as it is just imagination and it's not disruptive, you're okay. But if it is more than that, wanting to be another species could seem very odd to people, you should instead focus on yourself and find things you like about yourself and how you can be a better you.
Well, I won't have to worry about my problems if I was another species.
I agree that we fantasize sometimes of not having any problems, but I feel like if it becomes more than fantasy, then we may end up being irresponsible with solving them and we may end up not being happy and just constantly wishing that we are something else like a different specie. I do hope you find solutions with your problems so that you do think less about being a different specie.
