I'm fine with you not getting the dreams if you don't use the tadpole. It's reasonable. You decided to not risk using the tadpole; ergo the tadpole doesn't get a hold on your mind and you don't get the dreams. You do get a reward: not being corrupted, which I assume (hope) will be important in Acts 2+ of the game.
This is an entirely different situation than rushing to reach the Githyanki creche and not long-resting. There is NO benefit to speeding through the game without resting, only downsides. I can't imagine that in Act 2 it will matter how much time it took for you to reach Moonrise/Githyanki creche, as there is no indication that time or number of rests is being tracked. Furthermore, the majority of the downsides to rushing don't actually make sense. Why must the companions only talk to us before a long rest? We could just as easily have conversations on the road or while short resting.
