as i read your note , i had a most pleasent feeling over me , ,, i have experianced the same thing and it is something to do with astral travel,, i had the same vibration thing for a while and funny thing it was at the start of my awakeing, i feel you do a lot of work when your asleep and you travel as well , ,, but one thing i do see is thet there ia a female figure ,like a granmother who is standing beside you when you wake up ,, she has a granmother feel to her , and i takeing it that she is a guied and a graet teacher as well , i get the name mary from her?? i allso get a head ache from her like a stroke or tumore,, dose this mean any thing to you , the energy you are feeing could be this guied who is with you ,, do you see her when you meditate ? to me it feels like your on your way ,,wakeing up so to speak,,, but this dosent answar your question about what you can do with it though dose it , it certainly is a good thing though to keep track of the things you feel and see as i feel theres alot more to come hope this helps abit , daydream
