Write down your day's events as a way to let go of them for the night.
Think, say, or write that you are letting go of everything that happened that day.
Gentle stretching before bed can help us let go of the day and get our bodies ready for sleep.
Try some mindfulness meditation with the goal of falling asleep.
To avoid sleep disturbances from electronics, imagine a white light shielding them.
If the energy from your electronics is keeping you from getting a good night's rest, try visualising a shield of white light encasing them.
Plan (say it out loud, write it down, or just think it in your head) that you are sleeping peacefully and getting a full rest from the act of sleeping.
Intend (aloud, in writing, or in your head) that you are sleeping peacefully and restoring fully.
