Flood in a dream

Biblical meaning from Hearing God's Voice in Dreams by Apostle Nicholas V. Mbanjwa

What it means

Defense and fortitude of the Holy Spirit; or satanic invasion and swift destruction.

The author notes the Hebrew text of Isaiah 59:19 has no comma — the flood should be associated with the Spirit of God, not the enemy: 'When the enemy shall come in, like a flood the Spirit of the Lord shall lift a standard against him.'

✦ When it is positive

The Holy Spirit's defense and fortitude — a flood standard raised against the enemy

⚠ When it is a warning

Satanic invasion and swift destruction

How to tell the difference

Context is critical — the author provides detailed Hebrew grammatical analysis to establish the positive meaning.
