Lucid dreams are not related to mental instability.
IMO those that have them are intelligent individuals far less likely to engage in violence than the general population.
Not uncommon those with mental instability are drawn to these practices though...and for that it increases the chances for Psycotic breaks.
Those who are intelligent often times loose that edge the deeper into this practice they go. Though they themselves aren't aware it's a slow downward slope...or that they appear less intelligent to those who know them well. They "believe" they are still in control....but obvious to others they've lost their edge of "intelligence".
I think it is possible that Jared may have experienced a psychotic break and confused that with “conscious dreaming”
When you read his “mind control” stuff he seems to think he is God controlling others
As to what he was studying there was a mention of poetry
Maybe the left should attack poetry for a while and see if that flies
