I had an incredibly strange nightmare last night. If anyone has any insight to its meaning, I would be grateful.

Last night, I had a nightmare that's been bothering me constantly since I woke up. Perhaps there is someone here who can give me some extra perspective on it's meaning, if anyone is willing.

In the nightmare, I was inside a house. It was night, and there were no lights on, and the moonlight shined through the windows of this small little room and this little alove inside the room. There was a dog I owned, and I was trying to get the dog to come out of the alcove.

But the dog was incredibly afraid of something. It seemed like the dog was afraid of something behind me, but although it was very dark in the room the moonlight was enough for me to see that there wasn't anything there that I could see. I couldn't seem to get the dog to come out, and despite my attempts to assure it that there was nothing there, it backed away into the shadows, afraid of something that I could not see.

Flash forward a little bit, I was trying to get some meat, presumably for the dog. For some reason I went into an attic with a light to find this meat. After doing so, I apparently also needed to get a.. detached door. Sort of like a screen door of a house. However, there was a problem with the door. I wanted to get the window screen on, and the window screen on it would not go on all the way.

...I have no clue what any of this means, but I feel like it means something important. Does the dog cowering in fear at something that I can't see mean that there's something that -I- should fear going on that I can't see in real life? Does the door and the screen I couldn't attach mean that there is something in my life that can be getting in despite my having figurative closed doors?

I am really struggling with the meaning here. When I woke up, it felt important, but I don't know what it means. It feels like there could be something going wrong with my life that I can't see. It's very mysterious and I can't quite pinpoint the actual meaning.
