Is it normal to laugh on your own?
Yep.Totally normal
Yes, laughing when you’re by yourself is totally normal. You might be remembering something funny, reacting to something you’re watching, or just enjoying your own thoughts.
Absolutely. People laugh alone at a funny video, a memory, an imagined conversation, or a thought that catches them off guard. Sometimes you don’t even need a clear reason—your brain just finds something amusing.
