dreaming again

last night i had a dream that i was hiking somewhere familiar and foreign all at the same time. but as i was walking i heard rattle snakes everywhere. and dangerous animals left and right. finally a huge rattler bit me. grabbed on to my left hand and would not let go. its face was staring me down. i had to squeeze my hand until venom came out. but my hand remained to lose feeling and was on the verge to becoming useless.
