My mother did istakhara for my marriage. She saw two dreams in two days:
D1. She saw white sheet of cloth, on this cloth there was a about one inch pink spot.
D2. She saw white plate. On this plate there were some left over sweets (berfee).
Audhu billahi min ash-shaytan ir-rajim
Bismi-llāhi r-raḥmāni r-raḥīm
Wa `alaykumu s-salāmu wa rahmatu l-lāhi wa barakātuh
The istikhara is positive and your marriage will be blessed dunya wal akhira.
And Allah knows best,
