Remember that apologising is different to saying sorry.
Dreaming of apologising: This suggests a feeling of inadequacy in some department of life; feelings of having acted against, or thinking of acting against your own strongest drives; a sense of not having lived your best; a sense that you are not living up to other people’s expectations, or that you are not liked by, or not as good as, other people; realisation of a mistake or lack.
Being apologised to: A recognition that some aspect of a relationship or experience has been, or is, unjust or unwarranted.
Useful questions are:
What am I apologising for and does this apply in any way to waking events?
Is this an apology I am giving or receiving, or is it an expression of guilt?
If being apologised to are you accepting or rejecting the apology?
