This dream is showing you that you have gone through some cleansing process, (white sheets) but you are reaching deeper into a previous perspective only to realize that when you were seeing the world through ‘rose coloured’ glasses, or from a flowery perspective, that you realize something tore through that and did some damage.
When you address the past, possibly an incident from your childhood, and you forgive, you will have fully removed that damage from your life and will get on with more peaceful rest.
I pray healing for you, AK, that all the roots from the past hurts will be fully addressed and you will have the grace to forgive so that you can move on. Peace to you in Jesus name. Amen.
