okay, this might be really idiot, sorry if this is TOO newbie lol

Today, after lunch, I didn't have lots of things to do, so I tried a WILD. I relaxed, stayed in bed as much as I could, and as static as I could. I stayed there for minutes, and minutes, and I felt something that COULD BE a SP. I was feeling kind of weird, my fingers wasn't moving normally(yet I think I could move them, I didn't try ) and I was seeing some "light waves" and listening a horrible sharp noise. and in a moment, my eyes was opening by themselves(?), I looked just for a second, and for that second it looked exactly like my room, so I close them up and tried again, without any results

The thing is: could that be a FA? or I'm just being silly?
I'll try it again when I have time...
