Thank you for sharing your dream/encounter with us. Please take everything that I share to the Holy Spirit as He Alone gives the accurate interpretation.
Could the first dream be a visitation/encounter as opposed to a dream?
The second dream shared could be a change in mind for your sister-in-law. What has she being dealing with or involved with? Do you now see a visible change in mood/character/lifestyle? If not yet, it’s a promise that a positive change is coming.
