I woke up woke one morning and was amazed to find that I had no idea where I was or who I was. You may also say I was amazed at not finding myself. I must have been in my late teens or early twenties.
Everything around seemed new, unknown. My memory was gone completely: my name, my identity, my past….everything. A clean slate. So you may say that in this case only 5 senses were there, and the sixth…well, the memory section of that was gone. The thinking and evaluating part was still there.
Inside 30 seconds or so ‘I’ was back.
