Sighting occurred when I was 9 years old ... I was lying in bed , at night , when suddenly , a bright blue light lit up the room , as if someone was welding with an electric welder, just outside my bedroom window .( My brother slept in the same room with me , but was not awakened. )

I got up , and looked out the bedroom window , to see what was cauing the light ...  For some reason, I thought it was coming from a B-52 bomber  ( we had them flying overhead constantly back then, being on the flight path from Westover Air Force Base, in nearby Chicopee , Ma. They had nuclear weapons on the base back then ...)  
Anyway , there was no way it could be coming from a plane, as it was coming from the woods ,directly behind the house . There was a " cart road there, that was the remnants of an old railroad track.That was where the light was coming from, but I could not see what was causing it ; 
I remember CLEARLY thinking it was coming from a plane , but why , I don't know ... then, i could sense "movement back there , no distinct figures at all, but, movement of a sort ,causing the light to change intensity .. shadows ,perhaps ... coming towards the house ...  and I suddenly got VERY tired , and for some reason, went to bed ! 
I asked my mom about it , in the morning, but she knew nothing about it ( my dad was working the late shift then ,and wasn't home .I had forgotten about that night , for ages , till I was watching something on the History Channel , that jarred a memory .. 
Then there was the time that My sister, brother and I " disappeared , for the better part of a day ; We decided to go for a walk  ( we NEVER did that before, or since )  anyway ... we were gone all day ... and all I remember was suddenly finding myself standing on that SAME cart path , holding my brother and sister's hands ..
And i remember being yelled at , by my parents , for taking my younger brother and sister out into the woods ,,, ( I was 9- 10 , sis was 6 , brother was 5 ) ...
Something happened that day , but ... I don't know what ...  There have been other "occurances at various times , but these were the two "biggies" .. there was another thing that happened ..  seems like a dream now .... involving one of those " Gray " beings ...   showing me something about Global warming , or something ,,, something to do with rain forests , coat hangers and an Electric drill... ????
