CMV: I think that some biblical characters were high on perception altering drugs.

Example: Moses was on mount Sinai. On this mountain you can find plants containing a strong hallucinogen called Dimethyltryptamine (combined with MAOIs, which makes it orally active) that causes intense visual and auditory hallucinations. 

* It's known for causing profound religious and spiritual feelings (eg talking with a higher being)
* causes mind beding time dilation (he talked about a burning bush that didn't seem to burn down but kept on burning)
* Moses also said that his skin was glowing with some sort of aura (visual hallucinations are known to make everything glow and increase brightness and saturation).
* He also said he heard thunder noises and trumpets and "god" speaking to him and commanding him stuff (also very common for people under the influence of DMT)

At this time people probably didn't know exactly how these drugs work and are prone to believe what they experienced was real.
This is the closest to a logical explanation I've heard so far.

All the symptoms you mentioned could be caused by combinations of extremely common factors: physical brain disease, mental illness, sleep deprivation, starvation, religious practices, poorly-kept food...I would assume you just have a personal interest in DMT that's biasing you in this direction. Even if he was on a hallucinogen, it could have been ergotism as easily as DMT.

Not to mention, what makes you think he literally had those experiences while waking? He could have been describing a dream, his imagining of God, or been speaking metaphorically.
