So what are dreams? If mind is the waveform, which I'm now taking totally for granted, then it's free of the constraints the body is used to. There isn't a dimension it can't potentially access or a section of the multiverse it's unable to visit. What the mind can't do isn't in question, it knows what it can't do, and that's not a lot. The mind has infinity to play with if it wants it. Most of us don't want it to go that far.
The mind in this respect is both a singular and a collective at the same time, as Light is a collective of photons while also being omnipresent - which is perhaps quite a feat for any life form. Hey, making hay while the suns shines, maybe I may humbly suggest that we dump the whole ‘parameter of life' questions and just get on with learning what we can about how life works, rather than gettin' bogged down with the details. Whether or not something needs a brain to be conscious is very old-hat now. Let's move on.
