Does Pregnancy Enhance Paranormal Activity?

I'm currently living in the North East region of the UK in a new building that's been standing for less than two years. I've resided here for almost one year and have always had the odd occurrence of noises around the flat, things moving, but nothing too drastic or fearsome until three months ago when I discovered I was pregnant.

This always seemed to happen when I was on my own - anything from the bin lid opening and closing in the kitchen (which is open plan and connected to my sitting room) to shadows on my sitting room wall, to the phone line moving on its own, cold patches around myself or in certain spots of the passage even when the heating is on full. Most recently which is really concerning me is my bedroom. I have a very uneasy feeling that I'm constantly being watched and followed around my flat and fear this more at night time when I can see a darkened area in my bedroom which seems to suck in light as I look at it.

On many occasions, I have woke in the night to switch my bedside lamp on to see the shadow hovering above my bed off the reflection on the TV but when I look up myself there is nothing visibly there. This is starting to startle me and would really appreciate some insight in to what could be happening and why.

My partner is quite skeptical about anything supernatural and always shrugs it off, but two days ago when he went for a late evening sleep before going on a night shift, I closed the bedroom door fully with all lights off in the room and I went and sat back in the living room whilst I left him to go to sleep.

Two moments later, he phoned my mobile from his mobile phone in the bedroom telling me to stop opening and closing the bedroom door (he was fully aware this was happening as the carpet is extremely thick and scrapes when the door opens). He witnessed the door handle moving and the bedroom door opening and immediately assumed it was me even though I was sitting in another room. We would appreciate any help with this please as it is starting to affect both of us now in the flat.

I would also like to add that whilst prior to my pregnancy I've "seen" shadows and had cold spots in the flat, that I have never felt scared or like something bigger and worse is going to happen until now. It's getting to the point where I cannot switch off my bedroom light and have to leave my lamp on all night just to feel safe and attempt to sleep.

Any help would be great.
