hmm this reminds me I saw a dream where its a girl who always sees future visions and unconsciously always changes her habits according to to the prediction to avoid harm ,
lile for example if ahe is gonna get killed in library then she would unknowningly change her hobby to sweing cloths at home , and she herself doesn't believe in this precognitive stuff .as they never seem come true .
but these unconscious personality changes , seems as a mood swings or other such odd behaviour patterns in her kins eyes . one day her sister tells her about her changes so she tries to go to the library ....and it happens
