frightening experience

Well the most frightening experience is not about ghost or similar things, it´s about the power of the nature...once I was on vacation in Mexico with my mother and we went to "Huatulco beaches", of course the place was wonderfull and one day we decided to do a tour for the near beaches of Huatulco, the tour was in a boat trip. we knew very beautiful places in that tour but the time ended and we had to come back to Huatulco, well here comes the worst, the sea began to put really bad, you know the waves were huge and the boat moved a lot, the thing was so bad that in one moment a shipmate fell into the sea...was an awful moment but the captain rescue to that shipmate...the trip continued for one and a half hour and I remembered the faces of the people all had scare...well this is my frightening experience...
