Yumeship contains these versions:Oc X CanonOc (based on you) X CanonYou X CanonOc: In English this is called an "Original Character", a character that you created yourself.Canon: It is a fictional character of some product, This means that it is official because it appears in that series, anime, game, etc.

(IMPORTANT) What is Yumeship Sharing and non-sharing?

A yumeshiper sharing: That person has no problem seeing other people pairing themselves, OCs or other canon characters with the character they like.
Basically "share".A non-sharing yumeshiper: is a person who does not share, does not want or cannot see other people pairing those characters with the character they like. It is important that you and they do not attack each other, just block or mute! It is better to keep the peace!!A selective yumeshiper: As it is said, he is a yumeshiper who is very selective, This refers to the fact that they can block other Yumes of their favorite character or interact positively with other Yumes of their favorite character.Yumeshiper mirror: This is something not very well known but it is basically based on: If a yumeshiper interacts with a sharing, it will also have the same sharing position. Now, if you interact with a non-sharing person, this will also be non-sharing.
It fulfills as they say "mirror".Is yumeship okay?Of course! They are all valid as long as they are completely legal and do not affect the person's mental health.
It can be quite a positive thing, in the case of several artists, they improved their skills by wanting to draw themselves alongside that character they like.It's important to remember that you shouldn't attack each other! If you disagree (whether you're a non-sharing or someone outside of yumeship) you should just block or mute.
