Its possible you are self soothing, a need or a want, I have a safety blanket at bedtime, even in the summer, even when its very hot outside, my h cant understand it, I also have a stuffed animal on my night table, I have many stuffed animals. Its not abnormal, maybe out of character for you, but , maybe your (inner child) if you believe in that, ( i really have a hard time grasping the whole idea on the inner child) but if you do, then maybe its trying to tell you something . Hugs.
