Dehydration is the process of water being removed from a thing or a person. Dreaming that you are dehydrated could represent that you are spiritually dehydrated and in need of God.

Positive: Dreaming of dehydration could mean that God is about to provide for you where you are thirsting.

Negative: Dreaming of dehydration could mean that God is revealing to you that you are dangerously spiritually deprived due to a lack of the Holy Spirit.

(John 4:13-14; Isaiah 12:2-3).
