A Great Abyss and a Glass Arrow

This is a reoccurring dream of my youngest daughter.

She was with a group of people who stood on one side of a great abyss. They all needed to cross to the other side as that is where their tents were. There was only one place to attempt to cross. On either side was extreme danger. In earlier dreams they were unable to cross, but finally in this one, they made it across on hand-gliders.  Once there she and an old friend, who she knew from school many years before, Morgan, were looking for each other. Morgan has been in a number of her dreams. He shot a glass arrow in her direction that landed on a table. The dream ended.

I believe the great abyss is the Great Tribulation that believers must cross over to make it to a place of safety. The hand-gliders are symbolic of YVHV's deliverance. The tents are temporary dwellings in which we may need to live in the future, like the ancient Israelites.  The name Morgan means "of the sea." The sea typifies the nations, those out of covenant, but I'm not sure if that is the message here. I tried to find a meaning of a glass arrow, but I could not find anything, and the Holy Spirit has not revealed any understanding. I found that an arrow in Scripture represents "the Word of God sent." Glass, referred to as crystal in Scripture would have been a treasure found in sand. Sand reminds me of YHVH's promise to Avraham. Gen 22:17

blessing I will bless you, and multiplying I will multiply your descendants as the stars of the heaven and as the sand which is on the seashore; and your descendants shall possess the gate of their enemies.
