psycho vs strong subconscious mind

have u ever been thru a situation like this?:

you cannot recall doing something, at all. it's not that you forgot, it's totally something else. it's like you've never did the deed.i have.few days ago.many would not believe.and i don't mind.
and the story goes like this,

it's about a few dollars that a friend would like to lend to me.i refuse.she insist. still i refuse (nicely of course,but this is not the point here)so subconsciously i refuse or don't want the money.then she left that on my study desk.i noticed it.i even picked it and count it and i remember putting it back.on the desk.with the thought "ohh nantilah pk.nk guna ke x." deep inside i did refuse to take it.
and then it's the next morning.i remember about it.the few dollars on my desk.but it's gone. i try to look for it like crazy, here and there everywhere. i even speculate that maybe she took back the few dollars (i know how bad i was at that time and i'm truly sorry) and with other silly speculations like mybe the wind blew them off,or  maybe a thief got into my room and took them(even to this extent) but i never recalled that i gave back the few dollars. i was struck when she came and told me "sampai ati" me: "sampai ati ape?" she:"sampai ati pulangkan duit yg **** bagi" and me, with the expression of the-most-severe-terkejut-beruk-i've-ever-felt i said "sy pulangkan??"
---ok, the story ends here---

what's being my concern is how did this happened? i didnt bluff when i said that i cannot recalled doing such thing,getting the few notes from my room to hers. yet how did the few notes goes to her then? deeply deeply i try to think. and it freak me out when i come to this two possibilities, it's either:
a) my subconscious mind was so strong and so influencing the conscious mind that i happened to do that unintentionally, without any memory of doing it.
conscious mind says: just let the money there think later, vs subconsciously: i refuse to take any money from others.
b)i was a psycho, i did give back the money because subconsciously i refuse to keep it.and i distort reality.so i dont or cant remember doing it.

and now, i still cant remember it,even a slightest bit of it.
