Ohhh I’m a big fan of sleep pillows- I always have a little lavender pouch under or near my pillow! If I wake up in the night, breathing in the soothing smell helps me get back to sleep 
I’m with Megan about the dream pillows- I don’t think I’ve ever made one specifically for dreams before! I do sometimes do Lucid Dreaming work, but if I ever get around to getting my hands on some mugwort I think I’d like to give a mugwort dream pillow a try.
I see Francisco gave some amazing advice and resources for you- I hope you’re able to make a wonderful dream pillow, @tasha89! Good luck and blessed be
