While in Mexico visiting my grandparents ranch near a lake. The area is well known by myself.

It was around two in the morning my cousin and I were having a conversation (I was back from a three year tour from Germany) It was a warm day, when al the sudden a bright white light in front of us appear it was glowing (bright white) we look at each other and said what is that, that statement was the last thing we remember.  
We have discussed the event with no answer. Since then my cousin past away (drown in the same lake not the same area while in vacation with his family over 20 years later)
Witness indicates that date of sighting is approximate.  PD
