i have experimented with this a lot and what i experienced almost every time (during the real heavy 20x hits etc) was that it kicks in without notice
i remember myself asking how did this get to what it is why am I going crazy? is this forever? all with a very weird bodyly sensation and a general "bad trip" feeling going on.. still: i was laughing and loving it and wanted to try again so i did

one afternoon i stayed home alone and tried very small,successive tokes of 15x extract in a pipe offcourse to build up effect
this was totaly different,no pulling or shifting
the visual remained constant,no wild trainride just me on the couch smoking and looking at elves,shapes,unexplainable ???'s and so on

(fyi: i once saw shakira flirting and kissing(towards the viewers(read: me)) in her video and i got soo excited by it i thought it was real. the crazy thing was that in that particular clip she doesn't do that at all!!!(believe me i checked it for a week after every day watching mtv)

all in all i guess this on one side a very controllable experience
yet on the otherside you take a hit to long or hold it in too long and you're crawling for protection)

always be carefull and respecting towards all things(especially psychedelics)
