Large portions of the theological teachings in the Bible are based on the result of visions – not ‘hallucinations’ – oh no my friend, visions not hallucinations. So visions - not out of body states or ecstasy or nirvana, just visions. What is the difference between a vision and an hallucination.
Not a lot.
In a hallucination we have our eyes open. In a vision we have them closed. That is the only difference.
The perception system normally takes images, sounds, smells, tastes and feeling sensations from the 5 senses and feeds them to our Conscious self for interpretation. But the composer is also capable of providing input that matches these sensations. It too can provide images, sounds, smells, tastes and feelings which it extracts from our past perceptions or takes from the wider spiritual world.
As a true composer it then constructs a ‘scene’ or a set of scenes’ suited to what our Higher spirit deems we need at the time. But if we have our eyes closed there are no images coming from the sense of sight, so the composer provides us with images. But note that these images may still get superimposedonto the input from the other 4 senses. So a vision can still result in varying degrees of mixed sensory input. We may suddenly see the figure of an angel in a glorious landscape, but wafting in from our 4 senses is the sound of your husband snoring, the taste of that vindaloo curry you just enjoyed and the feel of your dog licking your face!
