Are these symtoms of schitzofrenia?

sometimes at night when im in bed i think maybe just maybe there is someone out side my window peering in the room although they cant see me, i think the shadows could be someone but i tell my self na no ones out there but i dont know. and sometime i think i see a shadowy shape move in the corner of my room. im 13 by the way. oh and also my dad who i know longer see had schizophrenia
