What does my dream mean?

I had a dream last night where aliens had abducted me, i wasn't scared at all, BUT when I was on this chair they flashed series of numbers followed by world catastrophes such as; 9112001 and it would switch to a flash of the planes hitting the twin towers. 1271941 then ships being blown up by planes. 1261917 two boats colliding and then it fast forwards about 20 minutes and the one ship completely explodes (im leaving out about 10!) ill go to the last... 1262012 its just me lying in bed, im literally watching myself sleep then i wake up in the dream, i walk to the window and look out but it goes blindingly bright and a loud bang. then i woke up in real life. The part i find the weirdest is that all the numbers are so stuck in my head, all 13 groups. all but the 911 attack started with the numbers 12 and after searching these numbers i found out that the pearl harbor bombing was in December, when the imo and mont blanc collided in Halifax the date was December 7 1941 or 12/7/1941 this really shook me up because the last date was in 2012, i never believed in any of that but after my surreal experience im wondering what this dream could mean? (keep in mind the only date i knew prior to searching the numbers was the 911, so if i dont know what happened on those dates how could i put together images and exact dates in a dream.. its ******* weird.
