Well, first , I beleive the pole or stake that you were laying on represents Jesus[inside you] taking the beatings on His back for your healing, of which your back was healed, also according to Galations 2:20 we are crucified with Chist and it is no longer us who live, but Christ who lives His life in and thru us, we no longer feed our soul/flesh with what the world has to offer, but we feed on Christ and His Holy Spirit within us and we feed on His word. As you do this, you are dying to the world, the flesh and the devil, and you will be moving in to the powerful things of God, which starts with being filled with the power of the Holy Spirit, which , in your dream, was pictured in the people getting slain in the Spirit, then the pastor picked you to come up, you have been chosen to carry a powerful anointing and many lives will surely be impacted, and the Lord is showing me right now the gals walking outside the churh represent the lives you will touch, as you die to yourself and be filled with all the fullness of Him inside, and you will surely shine brightly in this dark world
Quote from something I read : It is not always possible to delineate between impalement on a stake, and crucifixion on a pole (with or without a cross-beam), since the same terms were used interchangeably over time (eg. in Greek,
stavros, even when a cross bar is envisaged, as in the gospels), and because there was no ‘standard’ crucifixion
Remember, we are crucified, dead to the world and the devil and what they have to offer our flesh/soul, if our soul feeds on the things of Jesus, our body will be peaceful, joyful, and happy[we are body, soul, and spirit] and we will become powerful in HIM!!! Hallelujaaaaaah!!! All glory to Jesus!!!!
