You sound like an interesting person... You seem way more advanced then me... But this is my first week in this world...

For an idea of story, you could have someone find out about Lucid Dreams and as they try they would get stuck in one... So they would be stuck in a Dream-ish world and would have to ask for help to the people... That's just an idea...

You could have a DC (dream character) exchange places with the Dreamer so the DC would take possession of the Real person's body and the real person would be stuck in the Dream World until he finds out how to come back in his body...

These are just to give you inspiration to something.. Sorry for my lack of imagination today

Anyways, good luck with this! You are well welcomed in this forum
