Exploring My Mind

Hey guys! Been a little while, but I'm kicking myself back into it to make sure I don't get out of practice like usual. I've remembered quite a few dreams in the past month, but none written down, sadly, or I would document them here. So, this dream was from two nights ago. It was very short, mind you, but also very vivid, and it led to a weird sensation.
I was in my room, except with my co-worker for some odd reason. He pointed out to me two dudes who were lying under my girlfriend's bed, writhing about on the floor and dancing. All I could see of them were their limbs, and I could hear upbeat techno music playing in a muffled sort of way, as if I was hearing it from a distance.
My co-worker and I started dancing to the music, and everything felt happy. However, things took a very eerie turn when we looked up from our dance and noticed that the two dudes who were under the bed were now standing beside it, looking at us like we were crazy. If the two dudes weren't under the bed anymore...then why whose limbs were still writhing around under the bed...?
As soon as we came to this creepy realization, I heard a loud cracking noise, and a bright light engulfed all of us. It felt almost as if a bomb was going off. I fell on top of my bed, my ears ringing, and my body tingling. And as soon as I hit the bed...
I woke up, slowly rising from my real life bed, while still feeling the ringing in my ears and the tingling sensation in my body. It went away in a few seconds, and everything was back to normal, but wow was that a weird and unsettling end to a dream.
