hey people

some weird stuff happen to me and would really like to know how this happens and why... one weird thing that sometimes happens to me is that when i lay in bed at night it feels as is someone takes the tip of their finger(which is quite cold), puts it lightly in the centre of my forehead moves in circles and other times in random shapes, its not scary or anything, its actually very soothing, when this happens it feel as if someone is standing in front of me even though i cannot physically see the person, and im pretty sure im not crazy
Why is this happenning and how??
would love to hear from any of you
and PLEASE dont judge me on my age
