Weird meditation experience

One time I was doing this meditation I used to every morning, I laid down after the lil session, drifting into mild sleep as I regained awareness post one such drift, I see in my room a huge python, I went into an intellectual shock as to how that's phsyically possible, before I cud think something else the python at an unprecedented pace coiled arround me and as it coiled upto my head I went into some deep tranclike state and jolted back into awareness only to find that nothing ever physically happened!.
