The aura does oscilate as you call it and its quite natural. It has a resonance that matches our spiritual ascension. The body usually brings the energy down through the crown and the body and out through the feet. This is why if you say the word ground to yourself you feel heavy within your feet.

You can get energy in other ways but that is about building up energy within the body.

It sounds like your going through an awakening - this means your energy vibration/oscilation has been raised and thus you now get a peek in what ever your developing etc. Your body should get used to it over time, and it should settle down.

If you meditate regularly you can feel the loss of all feeling in the body, infact you become like there is not body, you can rock, twist, spiral, etc.. Awakenings come in about once a year depending on your development practices.

Signs of an awakening:

None of your protection practices work
You feel the energy within yourself
Spiritual contact is persistent and constant
Burning sensations in the hands, feet or a feeling of stretching around the chakras
Seeing little sparkles of light- I call them fairy lights
Seeing orbs more often


I would try to ground yourself as much as you can and hopefully your body should adjust to the new energy vibration wthin about a week, if it doesnt then theres something else going on.
