I had a dream about being stalked through my phone. What could it mean?

For some context into my conscious life, I recently got a new phone because I broke my old one.

In the dream, I was lying on the same bed I was sleeping on, just tapping away on my new phone when I started to hear the camera shutter sound from my phone and quickly covered my cameras. I thought it was just some accidental glitch at first and thought that "It's a new phone, there's no way it's like that" but after a couple more shutters I realised it was a camera sound. During that, I saw my mother just walk by my window and she smiled at me. 

After that, the phone describes my room and the scene in detail, talking about where everything in the room is and even going as far as to describe my mom after she smiled at me.

Now I know this is an irrational fear, and a lot of my horror dreams often have something to do with someone interfering with my personal computer or phone and somehow stalking me through it or putting malware on it. What could that symbolise?
