how should i tell this?

i know ive told my girls about my experience w that "something" thingy a few weeks back. this was days after ive just came back home for the sem break. owkei, ive these small bruises on the legs and some minor scratches on the back. ive only noticed the bruises when i wanna take my baths, as for the scratches my sis was the one who saw them n told me about them. i mean, i can understand the bruises but then, the scratches? i know if ive had scratched my back, but then they were quite at the middle so i was a bit puzzled.
and then days gone by without anything and suddenly there was this one day when i was taking a nap in my sister's room (coz my room tend to get hot at noon)...and then i felt like somebody slapped my back, not hard but firm. i mean, seriously i wasnt faking it. i felt it. n so i was awoken by it n then brushed it off as nothing, n went back to sleep.
owkei..this one quite gives me the creeps i guess. last nite, me n my sis were downstairs to get us some helpings on the cake that my mother bought. then we went upstairs and i saw that my stepdad was sleeping downstairs. n so after we got to my sister's room, she went to lie down n i continued to on9 and watching movie at the lappie. then suddenly i heard my stepdad like, screaming like he was angry. i thought he was mengigau and having a nightmare or whatever but then suddenly he said the azan. i knew my sis heard it too coz she got up and started to go downstairs. i followed suit but then as soon as we got down the flight of stairs he got back to sleep again. so then i seriously thought he was mengigau.
then earlier today i asked him what happened last night. n he said he saw something was goin up and he was tryin to stop it.
damn. that gave the creeps after hearing it.
