Actual Presence or a Dream?

OK, I know this is probably a common story people tell on this forum but last night (or early morning, not sure, I was asleep) it felt like I was dreaming but Im not sure that I was, there was a presence standing right next to my bed and right next to me, I had my back to it anyway, I knew that it shouldnt have been there so I was quite defensive, I remember laying there, I didnt move, but I remember being able to think up something to say so I told it that I had a gun and if it didnt get out of my house I would kill it, still not moving.  I woke up and sat up in bed, then got up and went and checked the front door it was closed and locked.  Then I went back to sleep and dreamed the rest, in my dream the figure standing next to me was an aboriginal man ( I live in the very top end of WA) so he ran off when I threatened him with the gun and when I went to check my front door in my dream it was wide open!  Now earlier that night one of my neighbours across the road came over to tell me that he had seen an aboriginal man walking up to and looking in my two cars and boat out the front of the property, I dont know if it was all a dream because of what I was told or if there was actually a presence in my room and I reasoned it to be because of what I was told earlier in the night and turned it into my own story.  Either way the presence wasnt a good one and my defensive response worked and it went away.  Any thoughts?  Its troubled me all day!
