If you would have some idea of what the probable universe is like, then examine your own dreams, looking for those events which do not have any strong resemblances to the physical events of waking existence. Look for dream individuals with whom you are not acquainted in normally conscious life. Look for landscapes that appear bizarre or alien, for all of these exist somewhere. You have perceived them. They do not exist in the space you know but neither are they non-existant (sic), mere imaginative toys of the dreaming mind, without substance.
