Loss of time, and White to Blue Cloud.

Myself and my girlfriend had just picked up my best friend and his new girlfriend who had just gotten back to town, so we all took a drive up to the mountains and as we made the first turn we ended up at the highway at the other end of what is an hour and a half drive depending on your speed and we were just out for the drive, none of us heard any sound or saw anything in the night sky, our drive just began and ended, we did meet with someone who we thought was a serious ufo investigator but he gut took all our information and books we had on ufos and just vanished.
There was also an incident in 1985 when I lived in Nevada and 20 miles from the Nevada Test Site, ha, ha  it's not there (right), anyway myself and my girlfriend were taking a late night walk down the towns main road I noticed a white cloud above the desert roadway witch had a bright search light like a helicopter looking for something, then the light went out after about 20 minutes of flashing around inside the cloud, then the cloud turned a bright blue and slowly faded away into nothing and the night sky was again clear.
Weather this is interesting to you or not I felt I just had to say what I expirenced, 
thank you
