Some human beings fervently believe that at a given moment, 'All is as well.'  Now, if everything always worked out for the best, you might assume all is also in perfect order. One perspective would interpret this assumption as a paradox. You may ask, why? 

If you believe in Higher beings beyond you, such as angels, then, from their perspective, perfect order always exists.  However, from the position of humans who live according to perceived duality, life isn't in perfect order.  If this was true,  why would souls choose to be born human?  There would be no opportunity for lessons, no role for reincarnation. 

Why might you assume your situation is far from perfect? Life will not evolve as it should, until you choose to raise your awareness, to think and feel differently than before.

Many people aren't yet attuned to their own own consciousness.  Where this is the case, people are driven by unconsciousness, which is also susceptible to creating fears and nightmares.  You determine how attuned you are and how attuned you become.
