Three to four years ago I saw human-shaped figures walking through my house, mostly during the night, and always when I tried to look clearly at them, they disappeared. It was when I started to learn about energy work, then I stopped learning from some time, and during tha time I didn't see those figures.
And now that I'm learning about witchcraft, I'm seeing those things again, sometimes clearer than they were then, and I'm worried about it. The last three months were very harsh to me, things had gone crazy on almost every part of my life, but in the end, nothing of what happened was really bad.
I don't know if there is a connection between they and what is happening, but they surely give me creeps

They tend to stay on the same places, my room, my parents room, and on the living room, and this house is very old but I don't know if the owner had some attachment to it, they also appear more when I'm alone at home ( maybe because it's easier to notice them when I don't have anything else to focus), they also go away when a cleansing ritual happens, but they come back a few days later.
Thanks in advance!
