Hallucinations or not?

Hey 🙂

About a week ago, I started seeing and hearing things for the first time in the middle of the night. I saw a spider (which was 100% fake. I spent most of the rest of the night searching my room and couldn't find anything) and once even a face or something. Since that happened, I've been increasingly imagining things out of the corner of my eye, but when I look, there's nothing there. People, for example. I feel like I'm becoming paranoid or something. I constantly feel like I'm being watched at night, like someone is in my room.

I also hear voices quite often (as if people are talking in my room. But I don't understand a word. Sometimes I'm called, I hear someone laughing, and sometimes it's breathing noises that definitely aren't mine.)

Are these hallucinations? Or am I just imagining it because I'm getting worked up about it? I also called the doctor right away and got an appointment for therapy. But I don't know if I really should go because I feel like others need it more than I do, and I'm just getting worked up about it.

I haven't slept well in several nights and I'm constantly tired. I'm sleeping, but I don't feel restful. (They're not nightmares, or at least I never remember anything. I haven't had dreams in general for a few months.)

Has anyone had similar symptoms or experience with this? I'm really desperate. ://
