I had a dream and in it I saw bodies, alive but very weak, floating, leaning on pieces of driftwood in the sea. The sun was beating down and they were being circled by prey from above and below.

The people floating represented our family members who are backslidden and those who are weak in their faith.

Matt 13:5-6 AMPC
Other seeds fell on rocky ground, where they had not much soil; and at once they sprang up, because they had no depth of soil. But when the sun rose, they were scorched, and because they had no root, they dried up and withered away.

1 Peter 5:7-9a AMPC
Casting the whole of your care [all your anxieties, all your worries, all your concerns, once and for all] on Him, for He cares for you affectionately and cares about you watchfully. [Ps. 55:22.] Be well balanced (temperate, sober of mind), be vigilant and cautious at all times; for that enemy of yours, the devil, roams around like a lion roaring [in fierce hunger], seeking someone to seize upon and devour. Withstand him; be firm in faith [against his onset–rooted, established, strong, immovable, and determined]...

Devour- to drink down, i.e. gulp entire (literally or figuratively); devour, drown, swallow (up).
