Have you ever asked a name to a character in your dream? What name did they say? Was it a normal name?

In my case, the names they give me i never heard of them and sometimes the names are so strange that I think do not exist. Why are the names given by the dream characters so weird? Am I earing it wrong?
Some of the names which they gave me: The Black Osiris (looks like an egyptian god name), José Manuel de Casalães (i'm from Portugal and this is a normal portuguese name, but never heard of it), Diago Frago D'Erotiz (this is kind of a mixture between a portuguese and a spanish name and does not exist)
