here's what i would do:

1.research on schizophrenia over the internet
2.research mediumship over the internet, it may be people in the "afterlife" contacting you or guiding you, i believe it could be a "spirit guide"
3. check your family history, see if its genetic or anything, as
just finding more information about it could help you understand it better, and make your mind at ease

i wish you well, take care man.
