I create characters, become the said characters, think like the characters and eventually feel like I'm about to lose my real identity forever.
Daydreaming. Usually about some of my imaginary worlds. Or imaginary conversations and unlikely idealized future.
Exploiting the AI and finding new creative ways to blow up people in video games. And real life...
The normal things, like internet, movies, music, reading, writing, drawing, art, etc.
Going out. Usually alone, for a walk or sitting down somewhere.
More unusual things, some of which I covered in another thread here.
