Is it normal to do several things only when completely alone?

I talk to myself a lot when I'm alone. Since I work in the cleaning industry and sometimes train others, when I am cleaning at home I use the opportunity to practice how I would show another person how to clean something. I'm sure it would look crazy if anyone saw me, but it's a good way to practice, lol!

I also have weird habits of rocking back and forth in my seat, or from side to side while I'm standing. One entire side of my family is energetic and squirmy like that, and a relative of mine had the exact same rocking issue for years. I mostly do it while listening to music, and have a hard time not rocking in my seat in my car while listening to music.

Since I rode horses for years, I have done some funny things in a car from time to time like two-pointing (which is a rider's jumping position), or at least leaning forward, but not actually getting up out of my seat like in an actual two-point, over speed bumps (which actually feel pretty similarly to a horse hopping over a small cross rail), clucking to my car while trying to get up to speed, and patting it as I walk behind it. These were all merely out of habit and not intentional. 🤣

I also have a weird hobby of compiling lists. It's like a puzzle to me. I will randomly inventory every item in one of my collections off of the top of my head and sort it by item, when I purchased it, etc., or list off and sort data in a million other ways. I have Excel spreadsheets full of this stuff, and this is fun for me, lol.

I will also occasionally play my violin, which I haven't played seriously since 2012. I haven't liked playing in front of others since then. That's really only when I feel up to it, though, which is maybe only a few days per year at the very most, and I've gone years without touching it at all. It actually desperately needs new strings, but I haven't bought any since I don't play enough to.

You should totally do all that when people are present.

I talk to myself as practice for conversations I might have with people some day because i'm not good at thinking of words to say on the fly (i'll literally go blank for seconds trying to think of what to say if I just try to have a non prepared conversation) I also sing full force when alone & try random things to see if I can like cartwheels, jumping onto things from a stand still, etc.

Lol definitely normal at least in my opinion. I talk to myself way more and loudly when I'm alone, I sing horribly, I laugh and cry randomly, I narrate what the neighbors are doing as if I'm their voices when I look out the window etc. I don't really know if it's normal tbh but I do it lol

Try exercising?. Sometimes when I'm alone I chew on random things or walk back and forth giggle because I have so much energy and it's hard to cope. but yes it sounds normal

I'm never truly alone, God, and my Siamese cat are always with me.

I have imaginary conversations with people.

When I'm alone I go on my Spotify playlist.

Anytime I have time alone I start shadow boxing
