I liked Lynn's idea its just your own Chi and I want to add, maybe your emanations or energy aura circle (mixing vocabulary here.) Look at qi gong moves and chakra lore. Then look at maybe a few books on string theory and psi research studies. So it could be your own chi not necessarily a multi dimensional entity engagement or alien instead of both your chi, and, something else. Also look up studies or self blogs on kundalini see if that matches you (re meditation and light. however light patterns and colors they are recording are more complex shapes than like a flashlight when your eyes are closing.)
I really liked Lynn's idea that this may be a manifestation of your own chi.
Because you mentioned elsewhere you can be reviewing books and shows, maybe you haven't gotten to read this genre. Some collection or collage is more applicable than say a yoga class. Um speakling of yoga, have you done certain positions which may open certain chakras? Some folks say yoga positions (which you might call meditation) moves your chi, your own energy, into certain constraints or configurations like a circle eight or big circle or directs it to a certain spot- which may or may not be what a great master would recommend in any of our lives out in California I went to a class and we that move land. Yean I'm in California too. Some people go to masters or teachers or gurus and apparently do prescribed yoga routines as meditation, like a physical therapist, analyzes your muscles and tears or charts and charts a series of excersizes. Well this is what random evens in a commercial yoga group reminds me of- if it is true that yoga postures direct chakra flow, then I am lucky I haven't had a seizure or opened and closed chakras randomly- as are you. Just sayin. Don't panic. It could happen to anyone, probably does. California classes at the gym or even among co workers random access not counting you tube directions reminds me of someone randomly picking playing cards out of sequence from a deck, calling it a card game. We are lucky worse things don't happen ( if yoga moves are chi directing experiences opening and closing chakras like gates on a irrigation system moving ditch water flowing down from the the dam upstream /here the analogy gets shaky/ like um universal energy. It can flow like a hose with a spigot . You are utilizing yoga postures, or qi gong, or verbal affirmations or spells to direct it if you know it or not. Its your chi.
I think there may be safe things to do to direct one's chi/ try again. I think there may be safe things to do for yourself and your own experience choosing and promoting your life, that you can do which direct one's energy. Like patterns rhythms which are an effective or efficient or safe 'holding zone' or 'holding pattern' much like airplanes at an airport waiting to land. There are patterns or rhythms ( and breathe execersizes and yoga postures and qi gong postures and words or ideas /that would be prayers or spells or affirmations that change your participation in yoru own chi/ energy, and may change other parts of the universes' participation in your chi/energy) which are for "launch" "ready for flight" or a million zillion other challenges /adventures.
What you appear to be asking for, is the set point of safe holding zone/ for your chi/ energy. Examine your practice. See if there is a qi gong master near by or someone that does energy based accupunture (I met one who trained in China.) Don't join a cult. Just integrate your energy field or set your pattern- it sounds like you are asking for assurance about it. Note: finding your vocabulary roots, or your belief roots, words which make sincere authentic sense may make it easier. Not to communicate with others who are teachers, and advisors, but to have a base to work your own meditation prayer or spell / energy flow through, Some teacher's words or vocabulary are not the only way to speak about the subject, (there are synonyms or near matches in words you might already know, already use, as a reference point) and adopting a class leaders' vocabulary may ring with an inauthenticity within, bring, a a not secure balance experiencing your own energy/chi. Its like overwrote with somebody else' definition of the chi / are you an empath? Find your own vocabulary. The chi your're flowing can move others' paths-- in your body when you connect with others. Check Debi's ideas on protection, or grounding; it kind of refers to maki0ng your own vocabulary your own words your own past real authentic speaking - speak during the meditation or prayer surrounding you, rather than a frame of reference from a yoga studio's excersize maven (whose directions on the yoga posture were on the excersize, she was trying to move muscle groups from a a stack of moves she was flipping around like cards/ unknowing uncaring because she was disbelieving in chi in energy in chakras that she was directing energy flow randomly or leaving it flowing like a Tibetan master in random suburban strangers.
