I daydream. I have insomnia and keeping my mind on something other than sleeping when I`m trying to sleep seems to help.
As for my daydreams, pretty much anything that keeps me thinking. Be it what I did that day, fantasies, or I`ve even done mental puzzles before.
Thank you for uploading the things I have asked you for so far. If you don't mind, I would like to ask you to upload as many of these as you can please.
