strange blue light enhances IQ

I was a first lt investigator and armed supervisor for Globe investigations and was sent to the WESLOCK key and lock factory in south L.A. to protect an unarmed IN HOUSE security officer as he made his rounds.  The night before an in house officer was shot and killed by intruders.  We were stting in a prefab guard house about 15 ft by 15ft and I turned off the lights so we could see if anyone would come over the outside walls.
The unarmed officer sat diagonaly from me in the shack and neither of us could see each other's faces. (we were both caucasions).  
Suddenly the guard shack filled up with a translucent blue light and at that point I could see the other man's face.   We were both amazed.  I looked up at the florescent lights and they were off for sure.  I looked outside thru the windows and could see no source of the blue light.
After the light was gone I called the LAPD, asking if anyone hit a power pole in the area that could cause such a light to happen.  They stated no.  
I added this incident to the nightly report and we continued the shift.  I have no idea how this light came to be.  It lasted about 15 or 20 seconds or so.  
I did however find that my ability to play the electronic keyboard was greatly enhanced and later i was tested for IQ due to an accident in an armored truck when my attorney filed a law tort.  My IQ had increased from 117 (measured in the USMC in 1959) to 160. 
To this date I can not figure out what that light was.  I did not see anything in the sky due to being inside the shack.  My hand was definitely on my .38 revolver from the time of the light to minutes afterward!!!!  
Since I am retired now I dont care what anyone thinks.
Witness indicates that date is approximate.  PD
