The Holy Spirit has indeed taken you to a higher level so you were able to see in this level the huge snake while asleep. Enemies in this level are high ranking; they are rulers and principalities over regions, nations and cities.

I call this level " Stage2". You may read my article on stage2 warfare at http://www.globalwarfare.org.ph/contents1x/Intro_message/warfare_stages/warfare_stages.html

Rabbit

Your dream on the rabbit tells that you are called to set people free from the fowler's snare. As a stage2 warrior, the Lord wants you to engage high ranking demons and neutralize them from inflicting terror in the heavenly places over territories God wants you to cover in prayer. Now the rabbit is symbolic of those who are trapped and helpless. God wants you to help them not only in prayer but also in physical and practical ways as you are one who quickly asks and listens to the voice of the Holy Spirit for instructions.

Hi, my name is michelle. im 17, i deal with alot of similar warfare. when satan is scared he attacks you because he knows you are dangerous for the lord, and especially if you have desires and a heart to serve the lord. i have dealt with many of the same things, dreams...whatever and you need to take AUTHORITY of WHO you ARE in CHRIST! which means before bed to a bible study(you may get weak and want to sleep but dont) and pray outloud for protection during the night and for peace and pure dreams and pray for this protection and sleep with christian music on all night quietly and keep your bible close to your bed. Good luck, your sister in christ,
Michelle
