Unwanted entity/spirit?

Thank you for the kind offer, but it appears the incubus has left me alone but that wouldn't explain why my brother said he could feel something watching him or walking behind and following him until he went to sleep, where he could feel something touching him in certain places. As I was writing this I think I saw something on top of me as I'm lead down?

You could always try the old traditional way and use a honey jar ritual,
