I had a ghost who watched over me when I was an infant. We lived in an apartment in the Bronx (near the EL train and in the flight path of JFK, lol) and my nursey was in one of the bedrooms. My mom would rock me to sleep in a rocking chair, and then put the chair up against the wall when she tucked me in and left. Many mornings she would come in and the chair was pulled away from the wall and rocking next to my crib (and it wasn't my Dad because my mom is a super light sleeper and would've known if he left the bed).
Also, if the window was open or closed when mom left, and the room got hot or cold, the window would be taken care of (Ie if it was open when mom left and the room got cold overnight, in the morning the window would be closed, and vice versa).
I kinda like that I had someone watching over me when I was so little
