DUDE! yea i kno exactly what ur talkin about! i used to get that all the time when i first started and now i only get it when im really stoned.. i love it tho its so weird and ur right the only way u can really explain it is in "frames"
'tis a good thing, aye? But yeah its a funny observation. My friend used to tell me something about this, about two or so years ago when we first started smoking weed, he'd see like a giant TV shaped thing, he used the word frame occasionally. I miss the good old days of things happening on weed that confused me... now I just know that they're acid flashbacks...
