Weird-ass dream

Alright then, I had a strange dream a few weeks back, and it just scared and confused the s*** outta me. Here's what happened:
Me and my friends get an invitation to some place called: "Crayola Wonder Aquarium" no really, crayola wonder aquarium. That in itself is odd as Crayola is frankly the last company I think of when I think of anything involving fish. Anyways, in order to get to said "Aquarium" we had to go thorough a snaking hallway filled with odd stores, such as "Free herbal body massage", I don't know what that means, either... Anyways, at the end of the hall/mall thing, there was a door. A blank door you'd expect a janitorial closet to have. We entered this door and ended up in a roughly 6x10 foot room that had little glass museum-like cabinets in it , inside were old crayola products, going back to the 19th century. Across from the enterance was a second "janitorial door" we went inside and there was a dark, huge cylindrical room probably over 100 feet tall, and in the center was a giant, cynindrical aquarium tank, and outside of this tank was a giant, flying silver Arowanna fish. Around this room there were other aquariums with deep sea fishes, like Anglers and lizardfish. For no discernible reason, I sat down against a wall and my friend tells me to look up. I look up and see a swordfish, which, for some reason, scares dream-me into having to take a dump. I go to the aquarium's restroom, and inside there was a weird PVC pipe-thing with baby cuttlefish in it. Seriously. Anyway I now find myself back against the wall and my friend tells me to look up again, and I see a severed human arm, with a fully-formed face on the hand (this also scared dream-me, but this time, I see why) I look around the C.W.A. and see that a lot of "people" in the building are shambling around with their hands on the backs of their heads, and then I realize their hands are f***ing fused to the back of their heads! Needless to say, dream-me and his friends promptly left. As we left, the museum room now had 3 glass sarcophagi emplaned in the walls, each displaying a different horrifying creature, one with the hands attached to its head, one with the heads on its hands (it had nothing but a withered stump for a neck), and another that looked like 4-Lom from star wars. After exiting the museum room, we found ourselves not in the mall/hall, but instead the parking garage of a building, one located a while north of where I live. Then I woke up, scared. 

And that, ladies and gentlemen, was my weird dream.

This would make a great horror story if it made sense.
