Is the suggestion meant to be that this only applies in certain kinds of brain function areas (eg for continuous senses, ie sight, sounds, etc) The reason I ask is that I don't need to repeatedly dream of bicycling actions to be able to keep bicycling - I might not use that skill for a long period and yet I can still do it with accomplished ease when I resume it after a gap. This suggests that the bicycling neural area (and likely those for other similar skills, assuming there is indeed an "area") does not suffer the kind of neural take over they hypothesise.
