Freaked out

This just happened yesterday, so lately my boyfriend and I have been joking about "the demon that lives in the basement" because his mom said she heard my voice talking when I wasn't in the house. (I chopped that up to her hearing the neighbors accidentally because we have some new neighbors that live closer enough you can sometimes hear them). So we have smart lights in the basement and yesterday they kept going off at random times and changing their color to red a few times (which was the last color we had it on) but then the lights changed to blue. I dismissed the lights changing colors because apparently that can happen with smart lights and we just started using the auto dim feature. But the real thing that weirded me out was I was sleeping and halfway dreaming, I felt a pressure next to my ankle and it felt like someone was actually putting a hand on the bed to support themselves so I thought my boyfriend was getting up to pee or my cat was standing on me. So I get up halfway and kinda kick at the pressure and I swat at it to see if it actually is my boyfriend or cat but my cat was sitting comfortably right between me any my boyfriend and he was fast asleep. But as I kicked and swatted at the "pressure" (I forgot I left out that the pressure was enough to weight down the blankets as if someone was putting their hand on the bed) anyway the room was pretty dark since it was night but I saw a white ish mist kinda move up and disappear from the spot where I felt the pressure. At the time I wasn't freaked out at all but now it's morning, I'm thinking about it more and I'm like wtf.
