Some people do not know or accept that Idlozi is Isithunywa from the spirit world to us or to our physical world hence, one would dream or having a vision of Ugogo or Umkhulu giving them Isiphika OR...

Dream or have a vision of being given some kinds of Sangoma beads as both messages are coming from the same source (edlozini) with different spiritual gifts.

There is nothing like "Isithunywa_somuntu" . Yes, we acknowledge that Angels do exists but to us as indigenous Africans we are known as Izithunywa zika Menzi

There is a confusion that was brought to us by the influence of bible which makes people think isithunywa somuntu is perhaps an Angel not Idlozi lomuntu hence, someone People would say "Mina angisebenzi ngedlozi but, ngisebenza ngesithunywa."

And such belief system are indoctrinated by a certain religion philosophy when our Spirituality says idlozi is the one carrying spiritual message to a person. (Liyisithunywa) and undermining each other due to this small knowledge.

Infact, Idlozi lebandla is actually the one which is known as isithunywa as it is associated with a certain African churches but, the fact is that, it doesn't take away that it is Idlozi in the end.

Our African spirituality has been confused as a Religion, hence some people have Abalozi spirits or Umlozi and think is Isithunywa sebandla and Africans do not  Prophesy but rathet do Umhlahlo mistaken Prophesying.

Bear in mind that, Isithunywa is not a foreign spirit but is your ancestral spirit working in you also known as the Devine or Holy spirit in our later days since, idlozi elikhanyayo is holistic by its nature.
