Dreaming of the letter “D” shows a sense of failure or not measuring up to others in some way. This letter has associations with words like dark, death, depression and difficulty and might be a cryptic way of exploring a lack of fulfillment or ignoring how you are not happy. Its message is to ‘dig’ a little ‘deeper’ into something you may be ‘dismissing’ so you can make an adjustment. Tilted just a bit – and the letter “D” becomes a smile.
