What am I supposed to do though once I start seeing pretty fixed sometimes blurry images come into my mind. Such as the one I saw last night of Microsoft Word typing something?[/b]
try to maintain 'passive awareness'. i know that's a pretty vague, paradoxical phrase, but you'll know what i mean when you real-ize its neccessity while WILDing.

if you try to 'force' yourself into the dream, it probably won't work. if you stay patient and aware, eventually you will find youself fully in the dream...its a delicate balance at first, but it becomes easier with time.

when i first started trying WILD, i would usually get to the point you are describing, and then try to grab onto the images, or install myself in the dream, whereupon i'd wake up.

the WILDs in which i've been successful i stayed patient and let myself be 'carried into' the dream.

hope this helps, and good luck
