Is this strange, if it is, what’s wrong with it?

That's amazing. I did that on my own when I was young for the first few books I published. The fact that you have a friend that will do it with you . . . They're a keeper. That's a good friendship. Best of luck in your endeavors as an author!

Sound like a good friend. I don't think there is anything wrong with this, as long as it doesn't interfere with your every day life or your actual friendship with him or her. So act on, especially if it helps you with your writing.

Role play can be fun, but make sure it doesn't get too out of hand.

Maybe you could have a safe-word so that you always know where the game stops.

It doesn't sound weird to me, your creating a story, it's a good thing to test them out, see what they are like. I actually did some research on writing novels and many authors act their characters out to hear what they sound like etc. As long as you don't take it to far and make things awkward between you or anything, I don't see the harm in it.

That's just creative roleplay and is a common technique used by collaborating young authors. The safe word is a good idea, though.

I think it sounds fun. People do weirder stuff that's for sure!

I'm a writer too. In high school me and my friends in literature class liked to act out scenes in both plays and books (in college, there aren't such enthusiasts in my group of friends--in fact, most of my friends are dyslexic guys who hate anything that implies writing and most forms of art...or big words lol). I think you're fine. We're creative and thinking outside the box makes us great friends :) It's kind of like playing with toys, except instead of using dolls or teddy bears, you use yourself and any other volunteer. Not really a weird thing. It's something you like to do, so do it!!! And yes, don't let it get out of hand! Just have fun and be comfortable with it! :)

Thanks guys :) You guys are so nice and positive <3 and we don't really talk about boundaries cause they're kind of just established. Thanks for all the feedback!!

There's nothing wrong with this at all. In fact, it's very normal. On top of this, I am a writer myself, and I can understand different creative processes from that point of view. If it helps, when I write, I get myself to the most emotional state possible. Then I execute those emotions, as if I am the character, writing the story itself.
