I'd go further. I think (from experience) that you can reach heaven in a state of mind even in all those scenarios. In a sense we are conditioned to respond to external circumstances and we learn to try and ameliorate bad conditions from birth. (We hunger we cry and someone feeds us)
But true awareness of consciousness allows one to be in a state of joy peace and harmony within ones mind at any time and under any conditions One of the main things required to achieve this is to be able to surrender fear totally. Secondly to redefine ones reaction to pain PAin is unpleasant, but first it can be largely controlled by mental discipline and reduced by a calm serene mind, but secondly also pain tells us we are still alive The only time we sense nothing at all is when we are dead or in a deep coma and even in that case some perceptions may seep through. Thus pain is a good thing compared with the alternative. Third, to learn the mental diciplines necessary not to notice things like hunger or bodily discomfort, or if one notices them, just
to put them aside.
Delusional is about the only state I agree with you on. A person whose mind is not functioning properly, probably can't exercise the skills and disciplines required to reach a state of internal empowement and joy.
