Could my experiences mean iam going to die or that iam haunted? please help : (?

About a month ago i had a weird dream about my cousin whos dead and was telling me something but i acnt remember. In the dream it showed his two brothers later on in 5 years and that he took me 2 the future or something like that i dont really understand and dat either me or his brothers are going to die in five years. that dream really scared me and only told two y frends but they didn't understand me and didn't know what to say. now i keep seeing in the glimpse of my eyes sumthing or sum 1 but everytime i look focusing i dnt see anything and i feel like sum1 else is there and the other day i saw a crow and it was cawin and later on 2day i saw it again. wen i tel ppl i think iam scared that sm1 is there they think i being paranoide. i dont know wat to do because lately i cnt sleep an havin strange feelings.
