Meditation, sleep paralysis, spinal vibration I have meditated off and on since childhood, before I knew what it was, and since my 30s I have been interested in the spiritual concepts of Buddhism.  I had an experience in 2010 wherein I awoke from sleep but could not move, yet my eyes were open, not my physical eyes.  I could see a pale ceiling but could not look around.  I was aware of my cat half-lying on my stomach, and he was purring.  My ears popped, and suddenly I could hear differently, acutely.  I heard footsteps ascending my stairs and the swishing sound like that of a robe.  I heard footsteps cross to the left side of the bed.  I was frightened, and the hair stood up on end on my arms and head, but I deepened my breathing and relaxed.  I immediately felt a type of massaging, but not on my physical body, more the ethereal body, and also a warmth.  The light massaging moved from left leg and foot to right leg and foot to left rib area to right rib area, and then I heard movement toward my head.  The light in front of my eyes suddenly brightened, and my sinus passages popped loudly.  I felt gentle pressure like hands cradling under my neck, and this pressure began to lift my head and shoulders upward, and I knew that I was being assisted out of body.  Then my alarm went off and awakened me.  I sensed a vibrational peace which lasted several minutes.  Since that time, I have had several OOB experiences, always as I go to sleep or am awakening from sleep, some frightening, which set me back for a few years.

Recently, over the last 2 years, I have had several experiences after I fall asleep wherein I half awaken in that state again, and sometimes feel a presence near, but immediately I feel a very strong, pleasant, vibrational, almost humming flow of energy flowing from the base of my neck to the base of my spine and back again.  I always fall back asleep easily.

I don't know what is happening, and I have been trying to release any fear and simply let it be.  I want to trust that this is some type of healing or spiritual progression process, but I feel that I have no guidance.  Are there any Buddhist teachers who would be able to guide me through this? Any response or feedback would be extremely welcome!
Dont be too much stuck with spiritual experiences.

What you explained accounts for nothing except that now you know what all things are there beyond normal experiences.

Since you have asked this question on a buddhist stack exchange I will suggest you explore more on meditation and start meditating. 

There is lit more to experience.
