I sleep with a stuffed animal
That's interesting. Why do you sleep with a stuffed animal?
Because the thought of sleeping alone makes me feel lonely.
There's nothing wrong with sleeping with a stuffed animal if it makes your feel more secure. Sleeping well is important, and if that improved your sleep then I think you should continue. It's not something that I've ever done, though.
I'm an adult and I like fun things. You should try it because it's great to sleep with them.
I'm glad to hear that you like fun things. I'm not sure if sleeping with a stuffed animal is something I'd like, but I'll keep the idea in mind.
