seeing apparitions in a dream?

To begin, i dont think I am psychic or anything like that. I had a vivid dream that people (all strangers) were trying to break into my house. I saw them through the windows and was terrified. I told my husband and he said there are no people outside. I would look at the people (thru the glass), turn and face my husband and describe the intruders, then when I'd turn back to look at the people, they were gone. That process happened a few times out different windows. I was very upset and told my husband I think I am going crazy because I see people and I hear them knocking really loud, even though you can't. The dream ended with one man at our door, and my husband said, describe him to me. I began to describe the shirt he was wearing, it had wavy designs on it. I reached through the door and tried to touch the man, and my hand went through him and he disintegrated in front of me. I told my husband the man disappeared when I tried to touch him and my husband said, I told you they werent real. When I saw them they were solid, not transparent or ghostly. IDK why but this dream is bothering me.
