Hi Dr, My relative felt very scare, holding me tightly, high heart rate(130), blood pressure very high(164/90), sweaty heavily on his palms. He said some spirit was after him, this episode last 2-3 hours. After that his heart rate and blood pressure were back to normal, no more sweaty palms. The same incidents happened twice for last 7 days. He didn t take drug or substance, but he has been taking depression drugs for more then 10 years. Look forward to you comment. Thank you. Roger
