No, there was no special concentration or call from the Mother at that time. It was at a time when she never sees anyone, so evidently she would not have put such a force upon you, nor does she usually exercise her power in this way. You did well to resist the impulsion. It is always necessary to keep the inner perception and will clear, conscious and in perfect balance and 
never to allow any force of impulsion, however it may present itself, to sweep without their discerning consent the vital or the body into action. Whatever appearance they may assume, such forces cannot be trusted; once the discriminating intelligence gives up its control, any kind of force can intervene in this way and a path is opened for unbalanced vital impulses to be used to the detriment of the sadhana. A psychic or spiritual control replacing the mental would not act in this way, but whatever intensity or ardour it may give, would maintain a clear perception of things, a perfect discrimination, a harmony between the inward and the outward reality. It is only the vital that is swept by these impulses; the vital must always be kept under the control of the intelligence, the psychic or when that becomes dynamic, the higher spiritual consciousness.
