flashbacks.. for me are more of a "slam/dunk"... probably different for everyone...

example.. was hit by a truck.. crossing the street... about 20 years ago..

present time.. walked across street.. slipped fell... in middle of street.. and.. went into shock... crawled.. to sidewalk... and fireman.. thought I had.. head injury.. wasn't hurt.. had "flashed back"... to previous time...so couldn't tell my name.. or anything... cause I was "back".. with the sounds.. the feelings... of the previous... time... a "slam/dunk"....unexpected.. normally.. a person.. that slipped and fell.. would just get up... and be fine...but the flashback...
