vivid dreaming

lately i've been having really vivid, clear dreams in HDTV. lots of detail. there were these spiders last night in my dream that i was watching very closely. they had lots of webs all over the surface of this river and one of the spiders ate a lizard so fast it was in the blink of an eye. all that was left of the lizard was its entire skin-- in tact. i picked it up and pulled on the tail. the spider had cleaned it out very nicely.
