Double check: Is dream catcher in place? Dream pillow stuffed with calming herbs? Teddy bear or totem tucked under sleeper's arm? Did the dreamer pee one last time?
Read a sweet bedtime story. Every Breath A Smile, based on the teachings of Thich Nhat Hanh, is a nice choice.
Ask, what was your favorite thing that happened today?
Turn out electric illumination.
Turn over rain chime box so it begins to ping.
Call in the four directions, lighting a candle for each. Announce that the dreamer now lies within a circle of protection and sweet dreams are welcome here.
Light incense or sprinkle essential oil around the sleeper. (Lavender and orange mixed together are very relaxing and can be applied to the feet.)
Remind sleeper to chase away any monsters or beasts that should come, or to sprinkle love dust on them, or to ask them what they want.
Kisses, hugs, I love yous.
Play a flute or sing a lullaby or read a bedtime meditation or put on a CD of meditative music or a hypnosis tape. Lovely.
Sleep is likely to come around this time.
Watch you don't use too many blankets. Or too few.
In the event of a nightmare, see if the dreamer will tell it so you can write it down. If s/he can draw it the next day, better. Ask, what else can you tell me about this nightmare?
Celebrate nightmare-free nights with pancakes and jubilation.
