It is the positions of the particles in Bohmian mechanics that are its "hidden variables," an unfortunate bit of terminology. As Bell (1987, page 201) has written, referring to Bohmian mechanics and similar theories,Absurdly, such theories are known as ‘hidden variable’ theories. Absurdly, for there it is not in the wavefunction that one finds an image of the visible world, and the results of experiments, but in the complementary ‘hidden’(!) variables. Of course the extra variables are not confined to the visible ‘macroscopic’ scale. For no sharp definition of such a scale could be made. The ‘microscopic’ aspect of the complementary variables is indeed hidden from us. But to admit things not visible to the gross creatures that we are is, in my opinion, to show a decent humility, and not just a lamentable addiction to metaphysics. In any case, the most hidden of all variables, in the pilot wave picture, is the wavefunction, which manifests itself to us only by its influence on the complementary variables.

I think he may be somewhat discredited as a physicist (you always are, if you engage in too much woo - something that keeps me as anonymous as possible on the internets). But he did, apparently, publish some papers where he worked out the geometry of neural synapses and concluded that they are consistent with the idea that synaptic firings might be controlled by quantum tunneling by electrons, and moreover a number of the dimensions and quantities related to neurophysical processing are explained by/consistent with this hypothesis. In other words, synapses are a kind of transformer that magnifies quantum indeterminacy to the level of macro-world biological systems. If there would be an interface between the ghost and the machine, this is where it would lie.

I'm not sure why, but at first I read that as "'Bohemian' mechanics."

21st-century directions in de Broglie-Bohm theory and beyond
A quantum foundations discussion workshop on the de Broglie-Bohm formulation of quantum mechanics and related topics is to take place in late August/early September 2010 at the Apuan Alps Centre for Physics, a 15th-century Tuscan former monastery in the mountains near the beautiful Italian city of Lucca. It is hoped that the meeting will be of great interest to anyone stimulated by the work of physicists Louis de Broglie and David Bohm, and by the directions their ideas have followed through the work of many people over more than eighty years. The meeting is being organized by Cambridge University physicist Dr. Mike Towler, who
owns and runs the monastery, and Prof. Antony Valentini of Imperial College, London and Clemson University in South Carolina. In its six years of operation, the monastery has become well-known as a unique communal venue where the community spirit and magnificent location have inspired a series of memorable meetings; we very much hope this workshop will continue this tradition.

De Broglie-Bohm theory is a 'hidden variables' formulation of quantum mechanics initially developed by de Broglie from 1923-1927 and clarified and extended by Bohm beginning in 1952. In non-relativistic quantum theory it differs from the orthodox viewpoint in that the notion of 'probability'
refers to the probability that a particle *is* at some position, rather than to its probability of being found there in a suitable measurement. From this seemingly subtle difference it is easy to show that - contrary to popular belief - QM can be interpreted as a dynamical theory of particle trajectories rather than as a statistical theory of observation. In such a formalism the standard paradoxes related to measurement, observation and wave function collapse (Schroedinger's cat, and so on) largely evaporate. The classical limit does not have to be presupposed and emerges from the theory in a relatively clear way. All the 'talk' is replaced by sharply-defined mathematics, it becomes possible to 'visualize' the reality of most quantum events, and - most importantly - the theory is completely consistent with the full range of QM predictive-observational data. While some believe the study of interpretational questions to be mere semantics or 'just philosophy', it is often forgotten that the location of the boundary between philosophy and physics is unknown, and that one's philosophical perspective can guide mathematical developments. For many people it is clear that de Broglie-Bohm theory should be studied, not only because it is beginning to make apparently testable predictions, but also because it has the
potential to suggest possible directions towards the next generation of ideas in theoretical physics.
... or ... is there dream after awakening?
there's a biologically known reason why it's generally difficult for us to remember most dreams, but I think it's reasonable to assume the "Buddhic self" (using that term/concept as it's fine and been introduced already) has no such limitation. So everything the dreamer became in the dream is remembered and influences the unfolding of the dreamer. remembered perfectly, and the dreamer may dream from that memory again, carrying on the narrative, adding to the memory, growing it further. The nature of the dreamer's memories are not different from the nature of the dreamer itself. and even dreams may dream.

It is sobering to consider that the afterlife might be a place where you care deeply about your daughter's husband's hairstyle.
That was my friend's reaction. She had not had a particularly easy relationship with her father, and was somewhat disappointed that he hadn't learned much on the journey across.
And I saw an angel standing in the sun, who cried in a loud voice to all the birds flying in midair, "Come, gather together for the great supper of God, so that you may eat the flesh of kings, generals, and mighty men, of horses and their riders, and the flesh of all people, free and slave, small and great."
Commencement Address at Kenyon University
By David Foster Wallace
There are these two young fish swimming along and they happen to meet an older fish swimming the other way, who nods at them and says "Morning, boys. How's the water?" And the two young fish swim on for a bit, and then eventually one of them looks over at the other and goes "What the hell is water?"
