Disorientation

I've never really thought of this as much of a ghost story until recently.

This incident happened whilst I was living at my grandparents' house. Not long after I had moved in, so about 3/4 years ago I was sleeping in my uncle's old room, who had unfortunately died a few years previously. I woke up in the middle of the night felling strange, kind of claustrophobic and disorientated so I reached out for the lamp on the bed side cabinet but I couldn't find it. This didn't bother me too much at first as my grandparents' house is on a farm so there are no streetlights and it's pitch black at nights. But then I started to panic because it felt like there wasn't anything behind me which is strange because the head board of the bed rests against the wall so there should have been something there but it felt like I was at the bottom of the bed, which I would have to be because if I was at the top of the bed there is a bedside cabinet on one side and a long set of drawers that stretch the length of the bed on the other and as I've already mentioned. I couldn't find the cabinet or the wall behind me. Eventually my grandmother heard me banging about and came to see what was going on. The bed makes a lot of noise when you move on it it's very old. She turned the lights on and I was sitting at the top of the bed where I should have felt the wall behind me and the cabinet and drawers on either side of me. It's only a single bed so I wouldn't have been far enough away from the sides of it to not reach either of these things. I thought that it was odd and that I'd felt strange because I'd panicked from not being able to see.

This seemed normal enough to me but as I've thought about it especially as I've only very recently moved to an area with street lights and lived most of my life in the country where it is pitch black at night that I can normally see at least a little bit at close range, but this was like blindness, and after my gran left the room I could see well enough to make out the bedside cabinet. I still only thought of this as possibly paranormal because I've only recently read about ghosts being able to things like this. Also if it helps me and several other family members have felt strange in that room it is occasionally very cold in there when the rest of the house is warm and my great gran saw a man standing behind her in the mirror as she was getting changed when she stayed in that room after I had moved out and she had broken her hip.

If it is haunted it's most likely not by someone who has lived there before as it's a relatively new house and my grandparents are the first people to live there, which means it's either my uncle, which I doubt because it feels menacing in their sometimes, or a spirit that has just stopped off there.

Any help on whether you think this is paranormal or just me having a weird but explainable experience would be greatly appreciated
