You feel in a comfortable armchair, you put special glasses, you push a button, you close the eyes and you add yourself/sink in a state of deep relaxation, half an hour later, when you extinguish the machine and you clear the special glasses to you, you feel extremely wide-awake and clear. Now my brain works much but effectively that before. My memory and my capacity to memory information have increased. Now I am but intelligent that does half an hour.
