This is an old dream I had almost 3 years ago i believe but it keeps coming to mind recently.
My husband and I had been asked to help his brother propose to his girlfriend. I recall being in a woodsy area , there was a cabin and a lake & my husband and I were hiding behind bushes as we watched his brother propose. The ring had a saphire gemstone. I recall waking up wondering if that meant his brother was going to propose soon (he still has not) and also being very confused as to why we were the ones he asked to help and why we were present when he did it because my husband is not close with his brother.
