Is there a sensible question in here somewhere?

Brain waves are classified by frequency: alpha, beta, gamma, delta and theta. Gamma are the fastest at up to 300 Hz. Beta are associated with wakeful alertness and are at 12-30 Hz. Alpha, 8-12 Hz, are connected with the "Ganzfeld" state which could be described as restful daydreaming. Theta are at 4-7 Hz and associated with meditation and imagination. I think they're unique to humans, or possibly all apes. Finally, delta waves are slow, associated with dreamless sleep, have a frequency of 1-4 Hz, and are, fascinatingly, sometimes still present after death for up to ten minutes.
