The main difference between your dream and your thought is the time of day or night.
The process is similar – magical games of the mind.
When you wake in the morning you see your dreams as just dreams.
Can you wake from this dream, now – the one created by every thought you have?
Sit comfortably in a quiet, pleasant place.
Notice your breath going in and out.
Every time you find you have got lost in a thought, return immediately to the breath.
Each time you return, your awareness of reality as against your dream, or thoughts, is sharpened.
