Trailer Parks and Lifesize Talking Grasshoppers

I remember the first dream I had when I was twelve. I remember waking up and going, boy - do I really dream like this?
So when I was twelve, I believe at the time, the song "Ghostbusters" was a hit. My dream began with a trailer in the middle of nowhere, in a large deep green field around 8pm at night. A couple were dancing in their trailer to this song. Slow dancing. The man seemed irritated at this, while the woman was smiling the whole time and happy she was enjoying herself and her husband.
Suddenly she hears a noise outside. She leaves the trailer, and walks out into the field in the dark. The music grows faint and it is suddenly silent. She is in total darkness. She sees a glow from beneath the ground, and bends down to look at it. The glow begins to pulsate. The glow is a bright green, flashing off and on. Fade to black.
10 years later.
The trailer park is gone, and on this ground that used to stand a grassy field, now stands a middle school. She is now a music teacher at this school, and is watching her class sing in the auditorium for hundreds of proud onlooking parents. She stands in the back of the rows, watching. She suddenly sees an open door in the corner of the room behind the stage where the kids are performing. She goes behind the stage and see the door, wide open, leading to darkness. She hesitates, not sure why she didn't see this door before. She walks through it, and into a void of black silence.
As her eyes get used to walking in blackness, she sees that she is walking down a long hallway. The hallway turns into a labyrinth, that begins to twist around. It is going further and further down, underneath the ground. She sees all sorts of old rustic black doors, all with locks on them. The walls around her are all black brick, with dirt and grime all over. No one has been down here for years, if ever. No human, that is.
She stops at an open door. Suddenly, she hears a shuffling from this empty dark room, and a grunting as some massive thing is moving. She stands there, not knowing what to do. From the darkness, comes a life size insect, looking almost like a grasshopper, wearing a black vest and hat. He stops and breathes raggedly. She stares back at him.
He looks at her. He bows like a gentleman, and takes off his hat. He stands back up straight, as she hears his wings shutter. She smiles.
"Welcome" he says.
