Many people would be surprised to find out that some forms of anxiety, restlessness, depression, intrusive thoughts, butterflies, itching, or things perceived as bowel issues, phantom pains, and more, are energetic interactions.
Knowing your regular or normal self can help. For example, if you aren't normally paranoid or anxious, and suddenly feel that way, and check for intruders or danger but find nothing your intuition would be warning you about, you are likely feeling the energy of someone else, or something else.
This is energy around you. Your heart's electromagnetic field reaches out quite a few feet from your body, and is very capable of sensing energy.
Absorbing this is sometimes not a choice, it is like being submerged in a cesspool of everyone else's crap.
I used to jog 5 miles every day, and while running I would stretch out my arms and feel for energy I can draw on, or energy I can breath in. You can set your vision straight ahead and run in a form of trance, allowing that altered state to guide you. These forms of energy can be heavy, or energizing, some of them burn like fire.
There are also multiple different points where energy can enter, or exit, and each of these has a different set of sensations, and these sensations can be totally dependent on how you are wired.
Because of spending too much time in the fuzzy dryer lint dimension, I can't stand touching peach fuzz. Yet chalk screeching down the chalkboard doesn't bother me at all. Different strokes for different folks.
When I was still quite young, I successfully knocked someone else out by focusing all the tired/sleepy energy feelings I could gather up and shoot at them like a laser from my third eye spot. It worked, but after he passed out and fell face first into the table he was sitting at, all the energy of my being started flowing out of the bottom of my feet. It felt like water flowing through me, and it drained me in seconds. Sound started to echo, I couldn't focus my vision, and I fell over like a tree, smashing my face into the table, and then bouncing my head off the concrete floor with a sickening hollow popping sound. I recovered quickly and stood up. My feet felt like they had fallen asleep, pins and needles. I went to the bathroom and checked in the mirror for the damage, but there was none. No bruising, no scrapes, but the table was destroyed. Whatever it was had obviously shifted me like some form of protective Qi, preventing damage or shifting energy.
Since then, I've noticed that most major energy fluctuations feel like fluids, or gravity shifts, with pressure changes, pushes and pulls, heat or cold, but they are always moving and fluid to me. One of the more interesting is when it bubbles while moving. Energy is often in a 'chirp' format, with spirals that increase and decrease. Some are like electrical zaps.
The last burst of panic, anxiety, or paranoia energy turned out to be my niece, hiding from a shooter at a mall, and wishing her uncle was here to save the day. So it was her energy, and her connection, and I had no clue what it was until I submerged myself into the fulcrum using my form of meditation and saw her face. That brief fulcrum visit still didn't give me enough energetic clarity to see what was happening to her, or why she was so afraid, just that my niece was in trouble. She was unharmed. I found out what was going on when I texted her asking what was going on, and she replied that she was hiding behind a Disney display from an active shooter.
