the Now

[Ohr Ein Sof]

Praying before going to sleep is surely a good thing in order to protect yourself.
Re that shadowy (astral?) figure, I would sit with it in meditation - ask your higherself or the creator about it and what should be done.
I am sure you will get an answer in one form or another, it may be an intuitive knowing. You will be fine

Yes. I agree and to add, the Astral plane is closer than one might know. The residents there are always trying to contact us and not all of them are good. But entities they are and can be dealt with fairly easily as long as there have been no open invitations given which would change things quite a bit.
