I.... had a dream... anybody have any idea if it means something?

Ok... so i had this one dream where i was at the local middle school and there was a whole bunch of people sitting around round tables that were all tered about in the gymnasium. i knew everybody around my table but one person... he was a geeky person who was from england... he was talking about his experiments with large bugs and stuff... than suddenly two of the security guards were killed somehow and there was an announcement over the intercom that two guards were killed by some rich english hacker or something, than i saw giant spiders and ants (LIKE THE SIZE OF SMALL CARS) running in the hallway outside the door and into the cafeteria (where there were a whole bunch of elementary kids) and than a whole bunch of screaming... none of the people in charge were doing anything even though the screams were yelling for help... the screams eventually died out and stopped... than the giant bugs started trying to get into the gymnasium where i was at...and the people in charge were still doing nothing... and than my alarm went off... :( and that was it
