For the people who think we can do this through dreams theres only one problem. When dreaming you dont make up new faces or new tastes or new anything realy. What you see in a dream is stuff you have already seen in your life. So lets say you just make a dream induced gaming thing were everyone has the same dream but everything will taste and look difrent because everyone has had diffrent experinces. Antoher issue with useing a dream state is that you dont remeber very many of your dreams and this is becuase when your dreaming your brain isnt trying to remeber the stuff you see its just trying to comple all the stuff you have in your short term memory and stuff it into the long term area. The only reason that your remeber a few is becuase that the snyapses by chance fire at the same time. The only way you could possobly utilize a normal body fuction that happens is the part that keeps us from moving. This would have to be amplified becuase other wise im pretty sure people will “sleep walk” has they are trying to kill a boss or something.
