Hi FalseAwakening..
Yes I experience this phenomena too.. I call it an 'anomaly'
, a tightening / pain at the top of the neck / base of the skull. My situation with this began more than a decade ago and continues to this day, although the intensity now is greatly reduced. Please allow me to be very clear about this, this is NOT a psychic attack/greeting. My perception in my own case is that it is my own fear, or stress response to [what I call] additional energy(ies) coming through. It is a brick wall, you could say, that I myself, due to unconscious fear instantaneously put up and keep in place. Another way to look at or say this, is that 1000 watts are attempting to come through my 200 watt bulb and the stress [as I morph into a 1000 watt bulb] is being felt.
My tightening, or pain has been constant, rather than periodic. A few years ago as the intensity was rising beyond my handling skills I sought help. Since then I have been learning to relax this area, as well as to be conscious of what it is that is Spiritually happening; as I am primed to be a channel. This lead to me being conscious of my out of body experiences, which from this point now occurred steadily at the rate of 2-5x a week. For three years I focused in on
this, consciously shifting into other reality systems, into other areas of consciousness.
It was only at the tail end of these three years that I realized what was behind my consciously shifting, in such great detail and so often. It was an Energy I simply refer to as 'a deeper layer of my being' merging with me. I learned at this point, that during my OBEs, on a frequency I had been barely aware of until now *[an aspect of my capacity is that I am able to to remain conscious on multiple frequencies simultaneously]* energies were learning to use my vocal chords. I am near fearless with OBEs, but I still remain uneasy being conscious while energies are speaking through me. The involuntary speaking takes some getting used to. I am currently on a sort of sabbatical. But I will be called to duty soon I am sure.
I hope there is something in here that helps.
