Dream Herbs/oils?

So I have a LOT of trouble just falling asleep, and hate using sleeping pills and other drugs.
One time my friend, her sisters, and her mum put lavender oil or herbs on their faces,behind their ears, wrists, etc.
They all fell into deep sleep and had such vivid dreams, i think they were even able to control them.
Any thoughts or advice on this???

i’ve heard they actually make sleeping/dreaming pillows from lavender and mugwort.
