Ephemer's original connection to Sora?

Does anyone think Ephemer (and other Dandelions) had some connection to Sora prior to Ephemer and company's rescue in KH3, which made that rescue possible? As if Sora's heart called out to Ephemer for assistance?

If friends are Sora's power, did Sora already met Ephemer in a past life to summon Ephemer?

If that's the case, Ephemer and Xehanort would have a connection, too...

If that's the case, I think Sora would have to be a reincarnated Dandelion...
