A white bright light in the middle of the night O.O?

i remember once when i was young i got up in the middle of the night went to my kitchen and their was a white bright light it was about 3 A.M. at night i thought it was a dream but it was real as hell i remember till this day i never talked about it but lately i started thinking about it and it scares the crap out of me. that white light was everywhere out side the window and it was so bright it was quite outside quite as hell. maybe i got confused with a dream i had but i remember it so well i remember witch of my memories are dreams and witch are real. and by the way i lived back then in a Village. are their any other explanations to this phenomena. because im starting to think i was visited my aliens but if i did why would they turn on such a bright light? what do you think?
