Ghost Dreams

The night before last I had a dream that involved ghosts. This seems to come from nowhere as I have n ot watched any ghost movies this week nor spoken of them. There are two things that come to my mind: My grandmother who raised me and died almost two years ago has been in my thoughts a lot lately because I miss her more as I meet new challenges in life and she is not here for me. Second: Would it be possible a ghost can possess someone's dream?
The first dream was a new house my daughter and boyfriend moved into. In real life we are looking into renting a huge house which hasn't given me the shivers yet but has much potential for eerie noises and tricks on the mind.
In the dream I was taking pictures of my daughter [age 2] and each picture showed a ghost running around with her, but its face was so weird. The eyes were too big and every picture the face was more and more distorted. The odd thing is it didn't bother me the first few snapshots almost as if I didn't realize what it was. But it got scary and kept chasing us and every snapshot it got closer. Soon Me, my daughter, and boyfriend [also, her father] were huddled on a bed in our bedroom shaking scared from the ghost. I woke myself up at that point. I tend to do that when my dreams become too intense.
Yesterday evening I was cleaning my apartment and turned around to reach for a chair and swore I saw someone standing right there starring me right in the face. It was my vacuum [stand up kind] But, the second look over I gave it I realized it seemed bigger then my vacuum. Last night I dream again of ghosts, those of whom did not seem as friendly but did not attack me or my family in any way. That is all I can remember from the dream as of right now.
This whole house moving deal may be affecting my dreams in some way because I am unsure about it. My boyfriends works a lot and it is four bedrooms, a barn, a shed, garage, basement with actual rooms used for storage farmers used to use, and multiple exits. After having these dreams I feel less comfortable living in that house and being practically alone 80 percent of the time.
