Yes, this is definitely a demonic spirit. Pray this “I cut off the head of the spirit of python and send the fire of the Holy Ghost consume it in Jesus name”
If you feel lethargic, always sleepy, no desire to read the word or pray this is also a sign this spirit is lurking around.
Pay attention to how you feel. This thing is a constrictor which tries to suck the life out of you.
Ask the Lord for angelic assistance to remove it completely from your life.
