Freaky and creepy

My son is 4 and is special needs. He CANNOT draw shapes, he can’t draw anything really except lines. My daughter is one and cannot draw not even a line. We are the only 3 that live in my apartment. Of course there’s also a little spirit child too that messes with us. Could it be the spirit?? *note that my sons crayons are in my LOCKED closet and on the highest shelf*
