What does this dream pouch do?

[InHonorOfHecate]

I made a dream pouch with the following:
Stuffing(the kind from stuffed animals)
Lavender Seeds
Rosemary
Dark blue strap
White and light blue fabric
I noticed it helped with particularly bad nightmares. Since there is rosemary, I think that it purifies dreams and the lavender seeds promote relaxation--and insomnia?
Anyway, from what I've written here, what do you guys think it's for?

Exactly what you said. To soothe and protect.
