“One can only know what occurs within the mind, which is the instrument or tool of conscious experience.   There is no such thing as "out there".   There is only our perception as inbound data. Everything is registered, just as it is. It is only via the mind that a selective representation of the data is created.   Thoughts are objects in the mind as things are objects in the world. The mind and the world are two separate dimensions, overlapping during the waking state. When you can so readily create a world when you dream, why do you believe the impossibility of your creating another world when you are awake?”
