A Presence!

Hey I just wanted to share something real quick. I hadn't felt this in a while but for 2 days now I've been feeling a presence around me again. I'm not scared (too much), but whenever something happens I freak out, to be honest. These sorts of things used to happen to me all the time in the past but something happened yesterday once again.

It was about 1 a. m. and I was going to bed when the window suddenly opened. I thought that maybe it was a draft or something but everywhere else was closed. I just know there's someone around me and it's seriously freaking me out sometimes. Please share your thoughts on what I should do or how I should react. Thanks in advance.
