Ghost keeps setting off my hallway motion detection light every time I go to bed | Haunted Spooky

A bit different from my previous video of the Cyc, I will post more as got a new bike and wanna make belt drive with the Cyc motor but...... Sorry getting a bit off topic there but I have moved towns into a new flat, been decorating so excuse the mess. I set up a motion sensor light in my hallway as there wasn't a light switch beside my bedroom door. I have Philips Hue lights throughout my house but thought was a bit excessive getting for my hallway so I opted for a motion sensor light I bought off Ali Express. All day the light is fine, only switching on when you walk within an area of the hallway but as soon as I go to bed, the light constantly triggers when nothing in the hallway, the door mostly closed just slightly ajar so I can see a beam of light seeping through the crack. I then go into the hallway but going to an area where I know the sensor can't see me and the light generally seems to not switch on if Im in the hallway. I have had a few other spooky experiences, but only one giving me the chills. I was standing in the hallway out of sight from the motion sensing, in complete darkness and this was at about 4 am when for no reason the smoke alarm which right above me goes off. I just wish I was recording that but that was at the time I was still trying figure out if things were actually happening or if I was losing my mind but that certainly clarified things for me. This is just the first video on such thing, I likely will upload more. I have actually recorded about six hours footage of the hallway at daytime and the light only goes off when either myself or the dogs walk in hallway.
