I've felt these before. About 80% of the time, they correspond to some form of solar event. I think I'm susceptible to sensing Schumann or Sun activity. Either that or it's 5g or some other radiation. 

Got sleepy like normal and was going to bed. Lie down calm and meditative. After about 15 minutes of lying there, get a short, massive spike of anxiety and dread. All these ideas and thoughts start becoming realized in my mind, mostly bad. Last 3-5 minutes. Feel a warm radiating feeling in my brain, maybe very mild vibrations too. Calm myself and try to relax. Bad feelings/thoughts pass, starts to feel like veil is removed from thoughts combined with body healing feelings. Start to see blue-black-purple spiral of meditative space get much more active. Feels like Spidey psychic tingles. Get a huge burst of energy, felt like I wanted to go for hike. Totally wired, can't go to sleep. Get up.

It's died down now mostly, maybe still feel it a small bit. Been experiencing this intermittently for a few years now. It doesn't always include the negative feelings, though maybe 30-50% of the time it starts off that way.
