Uncontrollable curiosity or ocd ?

for some reason, I suddenly became very curious about horror movies a few months ago (which i am very scared of) and could not resist my curiosity and watched many of them. (some really gory ones) Those horrible images stayed in my mind for sometime and I has flashbacks frequently. To say the least, i was traumatized. But now I kind of recovered and I no longer wake up or go to bed with horrible images flashing in my head and I am not curious about that stuff anymore. Maybe i learned my lesson but what started it all? Could it be a sign of OCD?
