Help w / Dream Interpretation

Sooo I just started on my journey with Lalas candles I finished halo 3 days ago. last night I had a dream that l was at my old friends house that I lived. Now it was a big house and me and my wife rented the bottom level for some months until we moved. However in my dream I was sleep and some how the neighbor was like there is someone coming to your door. Now we had a back entrance and at night with motion the lights would come on. So it appeared a tall man was coming down the walk way but all you could see is the shadow. So me and my wife got up and went upstairs and woke my friend up saying someone was in the back yard. So we checked the camera no one there. So my friends husband and my wife went to see what it was. At the top of their stairs was a pack of tissue that was not there before and in the kitchen salad dressing condiments was on the floor. It freaked us out cause the dead bolt was still locked and there was no visible break in. What does this mean ? Was this movement? I just thought this was a very odd dream ....
