What could this dream mean?

i used to have this re-occuring dream where i would be walking through my house and then all of this sudden i would come to this huge hole lined with steel that appeared to be a bottomless pit. a really deep loud noise would be emmitted from it and i would always look down and feel frightened of it, im not sure why but it scared the crap out of me. in a few of the dreams this guy with crazy hair would be standing on the ledge next to me just looking at me, once i think he told me to jump in, i didnt but a few times i ended up falling into the hole and just falling until i woke up. it hasnt happened in years but when i was around 10 it reoccured at least 4 times a maximum of maybe 15 times but could this mean anything?
