Would Sunny be able to go through a gate or would the nightmare spell repel him? Would it still create the pul?
NThe dream realm is real. It's just different worlds that have been absorbed by the nightmare gates. Basically it's-Dream realm is the consequence of the nightmare spell. Whilst nightmares are created by the spell that recreates a past event from the dream realm/other worlds. So to answer your question, sunny can still go to the dream realm
Here is what I think Sunless should do. If he has any soul shard from the 3rd nightmare he should us them to up grade fully the Puppeteers Shroud and Add all the enchantments from the Shroud of graceless Dusk. Frankly he should have dome that a long time ago. And if he has the spare Weavers mask from Ananke he should make so the flipping the flaw ability was an activating ability not passive. And give other enchantments like water breathing, durably and the hair changing color ability.
