My landlord knew what items I had in my bedroom. I never met my landlord in person

When I was 18, I was desperate to find a place to stay for university. There is a massive housing shortage where I live so I went on Facebook to find a room. Eventually a man from Egypt Dmmed me saying that he has a private room available. He told me that he moved back to Egypt due to being ill and decided to rent out his 3 bedroom house. He had no profile picture or any info on his profile other than his name.

He gave me the address to get a house tour with the current tenants that are moving out. His son was the one that let me have a house tour and that gave me the keys later via mail. This is a shared house with 3 students with the kitchen and bathroom being shared. I tour around, everything seems to be normal and clean in this house. So I ask the former tenants why they're leaving. They told me that the landlord is "a weird guy". But I think nothing of it and decide to sign the contract via email. I did not see his son after that house tour.

After signing the contract the landlord got my phone number on whatsapp and messaged me saying that he wants to build a friendship with me. I say that I'm too busy right now with school. He would call me sometimes 10 times a day and ask why I'm not picking up. He called me because he said he was lonely and needed company. Most of the time I wouldnt respond and move past it and pay the rent.

About a month after I move into the house, his messages became... stranger.

"I notice you have a heater and an airfryer on your table, could you please not use those?"

"Why do you own two laptops, that's kinda strange"

If this man claimed he is living in Egypt, and I have never seen him in person, and my windows and my doors are fully shut and locked. how did he know that those items were sitting on my table? There were multiple messages like this commenting on the kind of objects in my room or how I organized my room.

More importantly he would attempt to charge 150 euros more on the rent for using my airfryer too much in my room. Again, how could he tell that I was using my airfryer and not my roommates since I never brought my airfryer outside of my private room?

As for the roommates, they were pretty chill and also students, not from Egypt however. When I told them about the messages I recieved, they said they hadnt gotten anything like that and heard nothing from the Landlord. The roommates claimed that they've never been in my room or contacted the landlord. I don't believe them so I asked to see their whatsapp, and there have been no messages other than "rent has been paid". I tested if the roommates' key could open my door and it could not. They were also gone for majority of the day.

So I started to test him, I would put specific objects onto my table in my private room and see if he says anything about it.

Well he noticed and that's when I freak the hell out in the middle of a class lecture.

Then two days later after ignoring all the comments about the objects I placed, I get several calls from unknown phone numbers. I answered only twice. The voice vaguely sounded like the landlord and says to "come home"

I came home and the trash that I threw out that day was all over the front door to my private room.

Finally after nearly a year of dealing with this I finally found a safer place to stay and filed a restriction order against this Egyptian landlord.

I still have absolutely no idea how he knew what objects I had in my private room, or how that trash ended up in front of my door.

One friend of mine believes there was hidden cameras. While another believes a roommate was spying on me. But again I don't really know.
