I'll try to speed this up as much as possible so we can get to present events.
And Fede, at least I think I get your point.
I'm not the guy to over-analyze things, to be honest I don't give a fuck as of why certain things happen. If it works and even is fun, why bother? Well, I like to experiment on some things, but not too seriously.
So I don't think I overly limit myself by rules but you gotta admit that some sort of learning curves exist, meaning you get better at stuff with practice. Just imagining you can do anything doesn't work, at least not for someone like me ho has about zero control over his subconsciousness. Yes I know, belief-implanting might help, I need to try this when I find the time.
About dream logic aka nonsensical rubbish, that pretty much nails it for my hypnagogic forcing sessions and what I'd call intrusive thoughts in normal forcing sessions. Utter randomness. Sometimes entertaining but mostly just annoying as fuck.
The tupper moments are similar, yet somehow different. Hard to explain.
They seem at least a bit less chaotic and repetitive and more directed, coherent and tend to generate meaningful responses to my actions. But what mostly separates them from random garbage the brain spews out is that they are filled by a certain mixture of positive emotions.
So I'd say this state of satisfying semi-random yet intelligent interaction is what tuppering is for me in a nutshell. Well, of course it's all my brain doing this we don't need to argue about that. But I resent the view that it's the same as the randomness of dreams, even lucid dreaming. Beginning with the first distinct responses it felt fundamentally different from everything I had ever experienced. Even weirder, it was not a habit I trained (which was what I originally expected forcing to be), it just happened relatively quickly and quite unexpected. Getting crazy was easier than I thought.
