--regarding a comment above about the dreamer and how using the tadpole is essentially an inherently "dumb" thing to do... the dreamer has been changed to the guardian, and there is dialogue now that goes into what's going on. It's not the same scenario as it was. This is no longer a mysterious dream persona who may or may not be the tadpole and who can't seem to give a straight answer.
There are so many massive conclusions people are jumping to. It makes me wish I had bought stake in that "jump to conclusions mat" I heard about years ago. Sales for that thing must be skyrocketing.
Yeah right.... please forgive me for basing my conclusions on the actual evidence. Without using the tadpole, you won't have the dream, so if that dream is now somehow reassuring - which granted, I can't say for certain since I've only seen it in a video, though IIRC it wasn't that old - you won't see it if you did not already take the plunge. So yes, still seems stupid from a character's perspective.
Also, honestly, would you trust a figure that suddenly appeared in your dreams right after a tentacled monster put some worm-like thing into your head? You say it now explains a few things. I'll wait with my judgment until I've seen it, but it'll have some explaining to do.
And again, I don't mind not getting any of those powers. That's part of the story. Do I risk my mental integrity for them? Or perhaps rather not. It's more about the narrative elements since I think they're representative of the major theme of mental integrity and power this story has.
