i saw a ufo??

i was with my friends at the park hanging out as you do, when we saw a triangular shape in the sky cicleing something but it was quite low, so we were all looking at it joking around saying it was a ufo, and then a huge flash came from it and lit up the whole sky! this flash hapend about 6 times spaced out, what we thought was a ufo disapered then came back this happend about 3 times, then it jus disapearded. ever since then i keep having dreems about aliens and ufo's, my teacher at school says she was once ubducted by aliens and no one beleives her, but i am starting to now.
and today my brother ran into my room and told me that a mans pets were ubducted by aliens he saw it on gmtv, now in the last couple of days strange things have been happening!
do you really think this could have been a ufo? please write back to me and tell me your thoughts! thank you x
