Tunnel System
Two dreams were recalled upon waking, but neither very well. One survived long enough to be noted here.
Begin: This dream had several scenes in buildings and outdoors, but its most significant feature was a vast system of underground tunnels into which the group I was part of could withdraw. It was possible, by putting the mind in the proper mode, and thinking of a special individualized code, to be transported instantly to a location very deep within the system of tunnels, even from outside the system. I gather, though, that this was an emergency only technique, not to be used as a general practice.
End.
