Is it normal to talk to yourself and laugh?
Yep.Totally normal
Yes—talking to yourself and laughing out loud is very normal. You might be reacting to a funny thought, replaying a memory, or simply thinking out loud.
Lots of people talk to themselves, whether they’re working through a problem, narrating what they’re doing, or having a running commentary in their head that occasionally escapes out loud. Laughing at your own thoughts or memories is part of that; you don’t need an audience for something to strike you as funny.
It’s usually just an ordinary quirk, and most people wouldn’t think much of it. If it feels impossible to control or is upsetting or interfering with your day, it may be worth talking it over with someone you trust or a professional.
