Recent dreams containing flank

I am walking with 3 people whose faces I can't recognize. They are abreast and slightly behind me. The middle figure holds a closed box that holds the answer to a question/riddle that he/she poses to the group. We continue to walk down what seems to be a cobbled side street and discuss the possible answers. Eventually, the figure holding the box opens it to reveal the other two who are flanking him/her. A brilliant white light shines from the box, but the hinged lid blocks my view the source. I am overcome with a powerful sense of peace and tranquility, but I am told that I cannot look at the light...it's not my time. I suddenly find myself at a table with old friend whom I have not seen in years and tell them "not to worry, everything will be all right" and I have a feeling of joy and peace.
