I would just paint, not wallpaper.

so what paint color do u suggest?!

Difficult to say without seeing the wallpaper and bedroom together, especially since we have to judge colours on screen, but I would say that the second one, the more silvery one would probably go lovely in your bedroom.

The floors, bed, bench, nightstands and walls are all the same color, and this is a problem. I would paint your headboard wall or the whole room white or dark tan/brown. You could also leave the wall color the same and change the nightstands to a dark color with artwork above the bed framed in a dark color.
