Sinking. Physically sinking into your position on the mattress. Body molding with pillows and sheets. Head and neck at the right angle, hips supported, back being held just right. Limbs going heavy, jaw relaxing. Cat curled up on your ankles just so. Mentally sinking into the calm blackness behind your eyelids. Drifting away, and not considering it too hard. Allowing that blackness to enfold over you as your sheets and blankets do. No lights, no sounds. Sinking down to peace that may turn to dreams, then back to peace. The cat remolds itself as you shift and sink again. Then it too sinks back into sleep and dreams and peace.
