I'm a history nerd and a music history nerd so I always want to think about going back and seeing early music and classical music performed authentically on authentic instruments of the time. Alas, the reality that I'm a woman always hits me when thinking of such things. It would not be what it seems like in my fantasies. Not to forget that also a lot of classical music was performed in courts or in events only for royalty.
Going back in time but only experiencing it as invisible might be neat. Otherwise, I guess if I really wanted to I'd do what many women in the past did - I could pretend to be a man. I naturally (unfortunately) have a bit of a wide frame, so I'd just need to tie up my hair and use a binder and I'd probably pass pretty well. lol. But the risk of being found out would be awful.
Otherwise, I'd like to go back and see how religions started. I want to see if there actually was a figure that Jesus was based off of. I'd want to see how in the world the writers of the Bible thought he was resurrected or if they're just all straight-up dishonest (or I guess they could have been tripping lol). I'm curious. I also want to see the texts as they originally were, and lost apocrypha.
There are also things in my past I'd love to change. My decision for college (which breaks my heart to say, as I'm so glad I got to learn as I did and all of the experiences I had, but, I was not in the right frame of mind. I was not thinking about the future, and I had no idea what my future was going to be like. I frankly didn't think there was one, so I was going to school purely for learning), certain mistakes I made with an ex I really loved (but things probably'd still turn out the way they have, I suppose. We were becoming different people.), and a very personal family matter unrelated directly to me that I dearly wish could be prevented.
There are many things I don't think I have the power to change. Like my grandpa falling for prosperity gospel/faith healing nonsense and not taking care of himself when the time came, but I wish I could do that, too. Curse those vile ministries (who have also now practically taken over my country).
