Only got a total of 4hr sleep last two days.i'm hallucinating right now and hearing voices (not the crazy ones) is this normal for just 2day no sleep?

No; NormalOnlyMeans: common, not any necessary relation to health. Late teens to early 20s is the most common age range for schizophrenia to become evident, be diagnosed; thus your observations are worrisome. Suggest focusing on both getting more sleep as well as seeking/finding professional help worthy of your trust on the chance these are signs of early schizophrenia.
