the Unseen Housemate

We just moved to this place about 4 months ago me and mom share the same room the other room I use as a stock room/work area, and my brother sleeps in a sofa bed in the living room. My mom wakes up every 4:30-5am and starts watching tv (morning show as usual and the news) while I sleep at around 3-5am for obvious reasons I do online home-based jobs at midnight till early in the morning. Normally there is just the three of us at home as I know I only cook for the three of us. One evening when mom was preparing for bed she told me she saw on her peripherals a young girl dressed in white in the bedroom but when she looked again there was no one there I never really paid much attention to it as I know me I don't really care much if there are spirits wanting to pass by the house as its already normal for me to see those or even feel them passing by, what bothers me is that whenever I wake up in the afternoon I turn off the fan and fix the bed, get to the bathroom and when I get back the fan is still turned on, and every time I asked my brother if he turned the fan on he swore he did not. either that or he is on the sofabed sleeping.

This has been happening continuously for the last 2 months and this month there was a tall slender man that I saw in my peripherals he isn't doing anything but when I saw him he just sat on the couch when I was typing an article it was a job thing. and I have a deadline that I need to meet within that night. He did not say anything, did not even made a move, nothing he just sat there waiting for something, I haven't a clue what it is till I looked at the couch and there was no one there, think maybe he gave up because I just really don't have the time to get scared of spirits.

The fan incident still continues up to now, tonight I stayed in my mom's room when she was using the computer naturally I had the fan on but as soon as I stood up I walked towards the fan and turned it off before I went to buy bread for tomorrow at the bakery outside the compound when I got back, as usual, the fan was on and my brother is watching a video on his phone, my mom, on my computer.

I will never really have a clue if the ghost in my mom's room is just feeling hot or what but do they ever feel what we feel? the temperature recently is very unstable it's quite cool during the evenings till early morning but summer hot during the afternoon, it does not feel anything like Christmas, but that is another story.
