Your dream is somewhat prophetic.
Go to YouTube and watch the videos from Mary Baxter, Mario Martinez and Bill Wiese about their experiences in hell.
In that place there are indeed demons who are poking people violently.
From all that I have seen and studied it looks like the worst poking goes to those who were pastors and preachers on earth, but they turned away from the Lord to seek selfish fulfillment and prosperity. Those souls are lying in caskets that can't open and there are holes all around the casket. Demons ram swords and other things through those holes. The soul can feel the pain, but they can't die. Yes, the feet are poked too. Research it yourself.
Does it sound awful especially considering there is no way out forever? Yes, but so is the rest of hell. If people only had an idea of the torment and horror that goes on over there they would be on their knees crying out and pleading for mercy.
Since you had a dream like that my only suggestion is that you give your life to Jesus Christ, repent of your sins and follow him wherever he leads you. Do whatever it takes to find yourself in heaven with Christ. Demons get great satisfaction torturing souls in hell. Don't go there. Jesus loves you. Receive him and the price he paid for your redemption.
How to accept Jesus Christ as your personal Savior and Lord?
It is the easiest thing in the world. Just close your eyes, focus on him and pray something like this:
"Lord Jesus, I repent of all my sins and I ask you to wash me clean. I am sorry for all the bad things I have done and the many times I broke God's Will. Please forgive me and fill me with the gift of the Holy Spirit. I want to belong to God. I want to be adopted into his family as his son/daughter. I want to get to know you. I want a relationship with you. Come into my heart. I give you control over my life. Please lead me through the Holy Spirit and make your Word real to me. Fill my soul with the peace that surpasses understanding and help me change so that I may lead a life that is pleasing to you. I want to go to heaven and I want to be called by the Fathers name. As of today I declare that I belong to you". Amen
