I was sitting watching tv in my living room not too long before the sun set completely when something moved in the sky and caught my eye. just with the naked eye i saw black odd shaped objects passing each other in a pretty small brighter area in the sky. they each went up and down into clouds but then emerged again as if they turned around and came out of the clouds again passing each other several times. they were different shapes, one triangular and the other more cigar shaped or maybe cylindrical. was hard to tell how many there were. they moved fairly slowly but i have never seen objects in the sky going in and out of the clouds,except planes of course, usually ufos just disappear into clouds and dont come out. i got the feeling they were practising or something. when i first saw them i knew these weren't planes or copters, weird shapes very black it got too dark to see them after about 10 minutes. they were sticking close to dark clouda.
