Talking to Myself When I'm Alone

Does anybody else talk to themselves when they're alone? And what I mean by this is being in scenarios and acting as if you're talking to other people in those scenarios. Does anybody else get caught up in their own imagination and make up different scenarios?

Update: Thank everyone for chiming in! It really made me feel better, and now I don't feel alone. I still question if something is wrong with me, but then I come back here and see what yall commented! So thank you so much!
