Twice Upon a Time

Some twenty-eight years ago, I was involved in a serious road accident with my small service van. Fortunately, I came out of it quite unscathed. However, during the following one and a half years or so, I experienced a most intense and strange adventure; so strange that I now look back on it and wonder if it really happened. Perhaps you can decide.
Most, if not all, science fiction stories depict very typical human circumstances fantasised by moving them to an imaginary different planet or time or both and prognosticating human technology. "Twice Upon a Time" does this also but there is a question as to whether it is fantasised. Fact can indeed be much stranger than fiction and you are about to take your mind into entirely new realms of thought experience; so strange that they can only be conveyed by written and word of mouth and not by any other media.
