Sweet Mother,
How can one distinguish a dream from an experience?
In a general way, a dream leaves a confused and fleeting impression, whereas an experience awakens a deep and lasting feeling.
But the shades of difference are subtle and many, and it is by a very attentive and sincere observation (that is to say, free from bias and preference) that one gradually learns to discern the one from the other.
