If you were to go to a healing room, you would typically enter a reception room where you would fill out a form explaining the condition or issue you wanted healed. Then you would go to a waiting room, which is sometimes called the "soaking room." There is no water involved. Rather, this room offers a quiet atmosphere for visitors to begin feeling the presence of God's love—to soak in the presence of the Holy Spirit.
In the meantime, team members would review your form and pray to discern the deeper need in your case—a need for forgiveness, perhaps, or for confidence in God's care, or some other spiritual need—in order to pray effectively for you.
You would then be called into a prayer room, which might be a simple little room with a chair, and two or three prayer team members. Typically, you would sit in the chair and each team member would put a hand on you. The team leader would pray for you silently and out loud, with the other team members prayerfully supporting the healing. It is also recommended that if the patient chooses to stand, someone stand behind them to catch them should they be overcome by the power of the Holy Spirit and fall, which is sometimes called being "slain in the Spirit."
