A couple of days ago I awoke at about 2:30 am in a panic. My heart felt like it was beating very fast and I had weird feeling in my solar plexus. I felt a bit confused and unsure of what was happening, being half asleep. I thought ok I'll use my home blood pressure and heart rate monitor and see what is going on. My blood pressure was all over the place from 150/105 to 135/95. Normally it is 115/75. My hear rate was between 95-120 bpm. Normally it is around 60 bpm when I am resting. The afternoon before this I had had a neurofeedback session and also had a pretty intense 5 hour workday. Which my normal work day is between 4-5 hours. I was finally able to calm down after about an hour of this erratic high metabolic or is it physiological activity and now two days later am feeling more like myself. My sleep the next night went well. I have a few questions: 1. Has anyone else experienced something like this before? 2. If so, please share what was the situation around your experience here or send me a message here. 3. Do you think there is any connection between this event and the neurofeedback session? I'm thinking there might be, as on a few prior occasions, the night of the day I have had the neurofeedback sessions I have had some pretty intense nightmares and woke up with a startle. Thank you in advance for your support and help.
