I think it means that you had a pretty weird dream.
What does it mean when you dream that you are dreaming and are awakened by deceased family members walking into the room to visit?
Probably that you are missing your deceased relatives.
If you can't find any specific meaning then it would be the same typical story. As Gator Blu stated.
-You missed your deceased family members.
-Lately, you thinking about them constantly
-You wished to see them again
which all are pretty the same. Probably you just thinking about them and missed them so your subconscious is responding to it.
Dreams are the playground of the subconscious. All manner of strange beasties frolic about. They are sometimes significant; more often they're just nonsense.
