Ok so what about a soulmate au thing where you share each others dreams/nightmares? (andreil pls???)

They sat atop a boring, plain grey building in the middle of a boring, plain world, the edges soft and the sound not spoken so much as known, and it was business as usual. It wasn’t every night they fell asleep to each other, but the night was fated to go one way, they always - eventually - met. The dreamscape varied, of course, sometimes influenced by television shows Andrew had watched or towns that Nathaniel had seen.
