Twin Vibrations?

[sterlingindigo]

The other night I awoke to a strange sound and found myself in the mind awake body asleep state. I could feel the vibes. As I brought my awareness to the vibrations, I sense they were actually twin vibrations: A stronger vibration intertwined with a weaker vibrations. Overall, they were not the quality (Strength) I would need to project so I fell asleep.

Has anyone experienced the twin vibrations before? Any thoughts or ideas about them?

Thanks,
