Very interesting… but, I’m afraid I’ve got some slight misunderstandings…
1.
Twenty minutes ? What would be the difference between these 20 minutes and when the PFC is fully activated IRL ? 
The moment I wake up I feel as normal and “logical” as possible. I don’t have to “snap out” of it like in a LD and after 20 minutes go and say “Oh yeah… it’s RL !” (|)) I know you said “because our world is logical in itself”, but going back to my first question… when waking up, don’t just all the neurons “fire up” at once and there we are fully lucid ?
2.
Why “accidentally” in brackets ? Can they fire “unaccidentally” - but just because they are somehow programmed to ? If this is all accidentally, then people should have DILD’s like one per year. I guess you can somehow stimulate these neurons to “fire” more, getting so more DILD’s - I mean a sort of habit - no ? 
3.
Even after an RC you still need fuel ? I’m pretty sure this could happen, so… how can you make use of more “fuel” ? Rubbing your hands and stuff like that ? Sounds like attaining lucidity all depends on weather the neurons want to keep firing or not… 
[size=150]Well formulated and informative on-topic ! Keep up the good work Mars, I’m really looking forward to knowing more !
