Surely jumping on the bed is familiar to you ?!
Dancing before bed?
Yes or no?
Try it.
Create your own jump on the bed and then drown yourself in a soft pillow and a soft mattress.
Imagine that you are a star and pull your legs outwards, stretch.
Gather them all into a ball.
You're a star again, then a ball again.
Roll around the bed, like you're jam on bread.
Really, there's a lot of jam, a lot.
Choose the most comfortable lying position.
Completely calm your body and imagine floating on the sea.
Your body is light.
Breathe slowly.
Eyes closed.
You're sleeping.
