The other day I had a nasty case of sleep paralysis .(you wake up and you cant move because your still under the effect of the substances that paralyze your body to keep you from reenacting your dreams while you sleep)
and i thought couldnt we use that substance to make a realistic virtual reality ?.
I know i m not explaining myself too well but the idea is that your brain would transmit the order to move ( a leg for example) which would be picked up by a device( capable of analyzing the information that your nervous system delivers too your muscles from the brain )meanwhile the substance mentioned above would stop the message from reaching the body therefore you would only move inside the program.
This has probably been talked about a million times before but more tan wether its possible im interested in how far away we are from managing it
