Freaky meditation?

When I was in the service on ford Island Oahu,Hawaii,our baracks were there during the raid on pearl harbor. it was a nice evening
I was in my room meditating the temp was a balmy 75-80* there is no A.C. at this point and time the area around me became as you stated cold and icy I had an intense panicky moment and got scared for 3 days i would not enter the room, My mother who aws a gifted psychic told me it was the spirit of a fallen sailor from the attack who was stuck between planes and seeking help from an intuitive sensitive person. Her insight put that into perspective as bombs did fall in the medical buildind and barracks on Dec.7,1941. Your experience is most likely the same thing as in meditation you are closer to the other side. Bless it and ask if it needs your help in moving on.
Blessings and providence:
