Is it normal to talk to yourself and act out when no one is around?

It's normal. It's only not normal if someone talks back to you.

It's good to know some people are as weird as I am. Thanks for making me feel more socially acceptable :)

i do that all the time. my mom walked in on me once when i was talking to my self and was so confused. haha. it was embarrassing.

hahahaha yeahh!! i rehearse conversations before i have them so i know what i'll say :P

I do it! Often talk and play the superhero -villian roles in the shower! Lol

i hope its normal, since i do it ALL the time. actually, i tend to do it when im shopping alone or walking around by myself. i talk to myself all the time, and sometimes start acting like im talking to someone else. most of the time, i just call myself a schitzophrenic, but thats not exactly helpful. just the other day, i was thinking about something and i started laughing for no reason. then i laughed at myself laughing at myself and it just looked like i was a crazy person cuz i was walking to my class at my college. i really think its pretty much normal, since everyone has their own quirky way of talking out/acting out whats going on inside their head :D

if it makes you feel any better, i do that too. :)

It's totally normal :)
I do this alot because I have my own room so it's my little stage..haha

I do that too! Often feel like I'm going insane, lol.

I do it all the damn time.

I am so thankful to read all this since I have animated conversations with myself when I'm alone. I sound like the main character in "Fiddler On the Roof" who would say, "...but on the other hand..." as he debated with himself.

I first started doing this when I was responsible for Profit Planning and had to figure out how to balance the corporate books and make a profit sometimes in the wee hours of the morning at the end of the year.

A year ago I took a bad fall landing on my head resulting in bleeding in the brain. They told my wife to watch for mood swings in the near term and, as usual, she went bananas and when she walks in on me while I'm having a discussion with myself, complete wuth animated gesticulations, she thinks I'm flipping out into la la land which begins to make me wonder if maybe behind all the melodrama, she sees something I'm not able to discern.

I know I'm OK but it's still reassuring to hear that others do it also. My beautiful, but screwy wife, worries about things other people don't even know about. Like the night I came home and the first words out of her mouth were, "Do you realize the world will be destroyed in five billion years?" Shazam!

umm... does any of you 'become' someone else in these imagined situations... I am never me, I am a zillion times improved version of me, should I worry?

Yes, it is normal. It's a way for your brain to practice real life situations if they ever do happen. You actually cannot control it. It WILL happen to you at some point, you can just hold it back.

i always put a scene from a TV show, learn the words, then mouth them in the mirror :)
