The program leader has just left. I have 4 hours until the evening person will get here while I'll be on my own

Although my deadbolt was still locked and I can't see a way it could've been relocked if it was unlocked, I swear I'm missing things in my main room too. My echo dot, hard drive, and powerboard all aren't where I remember leaving them within my room. I can't actually find them at all. I specifically didn't take them because I didn't need to (and in the case of my hard drive, I forgot to take it with me). Also, an old phone I had lying in a drawer is a lot more smashed than it was before, and was also on the floor.

I'm hesitant to straight up say this is his doing and amend my police report because I sometimes forget that I've moved things around, but I can't find those things anywhere, even in drawers, not that I really had any reason to move them at all. Also, nothing on this room is slashed up, which seems to be his trademark

I'm honestly terrified now though, and it's not even dark yet. I'm once again keeping a knife very close and planning to hide in my room until backup arrives at 9. I don't know whether it's better to stay hidden and keep my curtain closed, or sit at my desk and open the curtain so I can sort of see out (although I'm sitting not much higher in the window so I couldn't see much).

Also, he has an illegal motorbike, so I know he has a way to get here on his own if he wanted to. Of course that means every motorbike I hear makes me jump. I could also walk down to the bus stop and then spend the night at a 24 hour shop or something. But the worker won't be here til 9, and the bus finishes before then, so I can't really just leave until the worker gets here, unless I walk home which seems worse.
