I've thought about this some. My "name" is Isaiah588, taken from the Bible verse, Isaiah 58:8. That is THE chapter on fasting in the Bible. In this verse, it says "Then your light will break forth like the dawn,
and your healing will quickly appear;
I have wondered if the "light will break forth like the dawn" has something to do with our minds becoming clearer. I've read so much of those who have fasted and they seem to say this is something they have experienced. Maybe wild dreams from nowhere are a way our minds are clearing house. (??) Anyway, this is one way to look at it. It wouldn't be anything to fear, if that's the case.
