Is it normal to have strange dreams like this?

What I'm about to write is not the entire dream, but the portion that I wonder about the most. It was one of those dreams where I can recall every detail, sounds, smells, etc. I wrote it down as soon as I woke so that I wouldn't forget, and to "document" it, seeing as I often have insane dreams like this.
Does anyone else have weird dreams like this? And can anyone tell me what may be the meaning, if any?

Now, here's the dream, sorry about my rambling nonsense.

I walk down to a beach. I stand at the shore and stare out for a while, letting the water bubble around my bare feet...I have no idea where the hell my shoes are at this point. I turn and see a house, I enter and know I've been there before and know who I'll find if I go in the backyard.
In the said backyard, I find a little girl looking out at a forest about 150 yards away on the other side of a like eight foot tall fence enclosing the yard. I know she's locked inside the tall fence because there are zombies and monsters and spirits that roam the land and forest beyond the fence. I don't know where in god's name the beach has gone or why this child can't go into her house, why she seems to be treated like a dog.
We walk to the fence and stare out into the forest beyond. The only word I can think to accurately describe this scene is eerie. It is now nearing nightfall, probably around 7:30ish during the summer. Overcast, windy. You can hear the wind blowing through the forest and through the open moor that stands between it and the fence where we look on. There is a faint and almost distant sound of wind chimes that seems to be coming from everywhere. After a few moments of silence between us, the girl says, "Only boys can get in, not girls."
I know that she was talking about the spirits of the dead, although I don't know why girls are apparently prohibited from visiting the little girls backyard. After thinking about her statement a moment longer, I turn toward the house to go back inside.
I freeze.
Standing near the wall of the house is a fuzzy, almost smokey black figure. I know immediately who it is and what I have to do.
I bolt for the door.
The shadow does the same.
The figure is the spirit of a dead someone, and with these someones, you can still communicate and interact. Apparently this dead someone is Juice...yes, from Sons of Anarchy. If you do not watch this show, then disregard this, i guess. Anyway, the reason I say it's Juice is because while I'm running to the door, I keep thinking of him. Apparently I was good friends with him before he died, and I don't want to lose contact with him. Why would I lose contact? Let me explain.
Apparently, you must make it to the door before these shadow people do. Like I said before, you can still talk to, interact with, etc. with these shadows. If they make it to the door before you do, they will disappear forever, never to be seen again, and if they touch you during this race, something terrible will happen, I'm not sure what, though.
So I'm running to the door, in pursuit of Shadow Juice. I push myself as hard as I can, and I am now about even with him in terms of distance from the door. I realize that the little girl is still standing by the fence. I scream, in a voice that's not recognizably mine, "Come on!" over my shoulder. She doesn't move.
"Come ON!" I repeat, and she still stands there. I have no idea why or how having the little girl run with me would help me beat Shadow Juice.
Realizing I need to beat him on my own, I push myself as hard as I can, harder than I thought I could. I round the corner and see the door. I see that it is slightly ajar, and as I get closer I struggled to remember whether I have to just touch the door or if I have to actually make it inside. I'm getting closer so I have to decide fast. Closer. I push myself with all I have to run faster than Shadow Juice.
I can see him in my peripheral vision now. Blood roaring in my ears, I thrust my hand out, fling the door open as fast as I can and throw myself inside, skidding across the floor on my back without missing a step. I hit the ground and let out a blood curdling scream with the effort I just put forth and the fear of losing more than just a race to the door. As I slide inside, I am facing out the door into the coming night, and catch a look at Shadow Juice just as he reaches the door and braces himself against the frame. I see his face, blue and black with the colour of shadow. Emotion clouds his face, tears rolling down his cheeks and his teeth barred in frustration. His face is not Juice's, nor anyone's I recognize, for that matter. After about a second, he vaporizes into fine mist, then disappears into the air. I close the door, roll over onto my knees, bow my head to the floor, and start crying harder than ever. I'm not even sure why. I mean, I beat the damn shadow, he's not gone for food. I guess nearly losing your dead friend forever and almost getting touched by the unknown shadow forces kind of does that to you.

So, that's that. Any contributions and thoughts would be helpful and also interesting. I am open to your own interpretation. :)
