need some help

i think there is something wrong with me mentally, besides the usual. for the past month, even before my medication was upped (i think), i've been having trouble reading words that have double uses in the correct way. today i read the following: "if your dream featured a snake wound around you . . ." i read it like a "battle wound" not "the top wound up." i've been doing this so frequently lately that it's beginning to worry me. i have NEVER had this problem before. i'm not sure how to look it up online. does anyone have any ideas?
