Many people dream of being in more than one place at once yet, hold the belief that this is not presently possible. What if you shifted your belief system to assume it is not only possible, but you are doing this beneath conscious radar?
Quantum mechanics does not conform well to human senses. The way atoms, molecules, particles and systems function, is subject to uncertainty. People do things Science is currently unable to explain and repeat in a lab. You may still ask how this enables you be in more than one place at once. How could it be? Do some research to clarify a few things for yourself;
1) Who are the types of people who do this? (they exist)
2) How would you describe their motivation?
3) What do you note about sceptics? (name/job/ belief- labels)
3) Where do your life, philosophy and mindset fit in? (i.e. why do you desire to do this and how are you willing to evolve?)
Consensus in the "real world" is grounded in the idea physcial entities behold three-dimensional space. This said, the core experience of three-dimensional space is limited to the awareness of three perpendicular axes: North-South, East-West and Up-Down. This omits the time dimension and ignores any possibilities such as those explored in dream dimensions, astral planes and out-of-body experiences (OBEs).
Rather than take steps to convince yourself how you can be in more than one place at the same time, it is desireable to work the other way. That is, explore why you believe you cannot and systematically refute your own reasons. For example;
A) Disbelief barrier -- "I can't so I won't" idea must go.
B) Threshold of fear -- visual or new strategy required.
C) Misconception -- stop dwelling on the non-essential.
D) Dual consciousness-- realize you fragment awareness.
E) Uncomfortable with physical body-- learn to reverse this.
F) Reflex problem -- identify & step outside comfort zone.
G) Weak intent-- if you truly want it, you figure it out.
