It is probably the true Cosmic Self or spirit with its cosmic consciousness and power that you feel on a plane above the ordinary mind or vital or physical — what plane is not as yet clear — for what you describe is common to this Self on whatever plane it manifests; it is felt like that as soon as the being or any part of the being detaches itself from the surface Ignorance.
* The Self is met first on the level of the Higher Mind, but it is not limited to one station — it is usually felt as something outspread in wideness, but one may also feel a centralising consciousness in the Sahasrara or above it.
* A complete silence makes realisation of the Self more possible — but that can be had on the Higher Mind level far below Overmind.
