It seems more a distraction than a help. Even if true, it impedes intellectual process, yields no practisable knowledge, it does not empower even if you feel empowered. True ability comes from knowing how true descriptions of existence produce true predictions or precognisense. A source for knowledge that is more mystery than knowledge of its source is a danger and a hinderance. It undermines the will and confounds the spirit, that is to say, all the emotions, the consituents of human essence. Our secure place is in the here and now, future and past in proper perspective, contingent and principle conditions have value. To see the future immediately without knowledge of how it is, is to be a passive, powerless, careless, hopeless abserver of human reality. The distortion of past, present and future makes null and void all those positive qualities which would have been, but are now destroyed, broken humanity. Be anchored in the here now, excersizing, flexing, strengthening knowledge of history, strengthening senses (as Karl Marx said) as theorticians in themselves.
For your own safety, 'deja vu' should be understood for the same reason a venomous snake should be understood, or more mysteriously, an unidentified creature.
