Replying to Is my house haunted?

So my house has always had weird things happen in it. My parents have both seen things but never told me or my brother unless we brought up the subject with things we've seen ourselves.So here's the backstory:

When we bought our house, which was built in 1989, it had been sitting empty for over a year. Nothing bad ever seemed to have happened in it.

The old:

1. My dad tried to open the door to my parents room and it would budge. He pulled as hard as he could but it didn't move. He turned to look at my mom and when he tuned back and tried again it opened right up.

2. One night I woke up to the sound of multiple doors slamming. When I opened my eyes my door was slightly open and there was a figure standing in the doorway. It slowly backed away. I got up and went into the hall and all the doors were closed.

3. My dad has said he's seen "figures" of a short boy and tall man. No clue whether I believe him or not but we had a serious talk about this recently and he seemed very serious.

4. One day i was home alone on NS, of course, sitting in my room. My dads office is behind my room. I heard a few drawers slamming. I went in to see if it was my dad but all the lights were off and no one was in there.

The New:

My parents recently got divorced and my mom moved out ( I still live in the house with my dad and brother). More activity has been happenening since this.

1. A few days ago my dad woke in the night to the feeling that someone was "sitting" on the pillow next to him. He the felt this "thing" get up and leave.

2. Yesterday I got a yogurt from my fridge. I then went outside (to urinate cause im too lazy to aim for the toilet) and when I came back inside my fridge door was open. I had made sure it was closed completely because my dad is ocd and freaks out if we leave it open. It had suctioned closed.

3. Today I was watching a video on youtube on my desktop in my room. I paused it halfway through and turned off the monitor. few hours later I was watching tv in my dads office, behind my room, and got up and went downstairs to button up (im home alone) i.e. make sure doors are locked and garage door is closed. As im downstairs I hear talking. I walk around to see where it is coming from but cant find the source. I go back upstairs to find that the video is playing, from the beginning, on my pc.

I am still home alone but leaving for a friend because im a little freaked out. SO what do you think, strange coincident or possible haunting.
