I see the energy change coming from two main sources. The first source is very physically based. As the "red comet" (Nibiru) comes closer to earth, it pulls on the earth's magnetosphere and shifts and tugs on the earth and her gravitational forces. I see that just as the moon pulls on our oceans, the shifts in the magnetosphere pull on our human systems (much of which centers in our head/brain/eustachian tubes/nervous system). The result is this dizzy, sick feelings and usually involves a change in energy levels as well (it can be exhausting for the body to deal with this, and sometimes ultra energizing because it is embraced).
The second thing I am seeing is that there are masses of people that are spiritually advancing (at the soul level). They may be meditating, communicating with their higher self, feeling guided through inspiration, or having lucid dreams, but fundamentally they are evolving and expanding. I get that this type of expansion can also include a symptom that creates this feeling of your spiritual self being disconnected from your physical self. Almost like you are floating above your body, or your spiritual being is taller than your physical body, the two aren't in alignment. ( I see it like a shadow. Your being is yourself, but your spirit is connected to you like a shadow, but much larger). To someone that meditates often it can feel similar to a mild astral projection, but experiencing it while of full conscious mind. To someone who isn't familiar with that sensation, it can be like what people call "medicine head" when you have a cold.
In both situations there is nothing to worry. Try your best to stay in balance (drink lots of water). Realize that you are evolving for the better and this is our human 3D body "processing" the upgrade.
And that is all I have for this reading. Thank you. Love and light-
