Human like figures seen when closing eyes

I had that about 2 or 3 times and it began with me as with you with eyes closed but then as I opened I still saw them. there was a portal where I then was so that was what i was told they were coming from. i think too they can sense energy over there so if someone else had been there before them and i had seen, felt that, trying to get into my sleep, dreams at first, not one spirit only but two, different times, then they can move there i gather more easily. i asked for help to close the portal and have not experienced all these people, dressed differently too from their black sillouite looking self.
