I try to teach people this all the time for years but they never really wanna listen or believe its real but it is but more people have been noticing lately.
People and even animals have and can get spirit energy. Its been referred to as chi, holy spirit, aether, mana (in Hawaiian), prana etc… it is real.
Have you ever noticed how the chills you get when you hear a scary ghost story is the same synesthethic response you can get when a cool wind blows or someone lovingly touch you like get a massage (laying on hands)?
Yes it is energy and you can consider it blood flow and the electricity in your nerves etc… as it is also that as well as emotions.
The matrix movie is supposedly or at least partly based on the book simulacra and simulation. I never read it but I heard it talks about sensory feedback loops a lot. In the matrix scene with the cat neo has deja vu and the cat shivers. This is called TRE and also scientists psychologists et al have dubbed the synesthethic feelings ASMR.
If you can get this feeling all through your body you are doing well. Its your awareness and as you do it you will also feel more perceptive and aware. For example you might feel your spine become very pronounced in your perception and clear headed and able to think deeper. Its also very pleasant.
If evil spirits become aware you are doing it they will do everything in their power to mindfuck and gaslight you about it. But they aren't very strong as they once were now its much easier to defeat them so take courage and faith. You can rebuke any negative thoughts while you meditate its very effective. Cuss them out even. And yes if you do it enough you can start to glow and stuff. Also psychopaths cant do this because they killed the key parts of their psyche/brain like amygdala that you need to tap into 'source'. Thats why they are (energy) parasites.
Yes, again, this is real. Listen to me and do it. Chakras and stuff are real too but get the feeling and you will find all that out for yourself.
