Dream saves error?

What if...when error tried jumping into the void... dream grabbed his hand on time? He was able to throw error back up but he fell down the void himself? What if...he ends up in another multiverse a bit injured?

(Different things happening and possible different personalities etc

Along with they find out dream is alive and work together with a truce to get dream back home which will take them a long while until then enjoy dream being in a different multiverse for at least a year or so
