I need some guidance from a dream enthusiast/spiritualist...?

5 years ago, I had an extremely disturbing dream that has been scared to my brain and, until now, I have not sought interpretation or explanation. Me and my girlfriend had laid down early that evening, earlier than usual, as we are both night owls and this was close to 10 pm. We just both felt the sweep or call to fall asleep. I almost instantly came to within the dream. I was slouching on a couch in a modern looking apartment that is unfamiliar to me. I was alone and it was what appeared to be night. Every light in this apartment was out. There where 2 doors, one to my left and one directly in front of me. I appeared to be in the living room and the room to my left was illuminated orange by a street light through the window on the opposite of the entrance to this room. As I stated, I was slouched on this couch. The door in front of me was open only slightly but what was visible complete darkness. When I looked into the darkness of the door, I felt extremely uncomfortable. I couldn't draw attention away from the opening of this door and I was physically paralyzed as well. I must have felt a presence in the darkness of that room because I sensed something was about to come out of the door and right then, some kind of shadow swept across the floor to my leg and when it touched me, it felt like electricity. It felt overwhelming and dark . It pierced my body with such a jolt that it woke me up in a panic. This is where it get's truly messed up. My girlfriend had fell asleep with me and she awoke screaming at the exact same time I did. I thought I scared her from my screaming but after calming for a moment, I explained my horror only to find her own. She had the same dream under different cirstances. I will spare you the details but needless to say, this same shadow force had touched her with the same results. We were so panicked, we couldn't sleep until the next morning. It had been irking me for 5 years and I had been thinking about it a lot recently so I was hoping someone out there knows what happened that night, or at the very least can point me in the direction of someone who can.
