What does this dream me? large blue spiders?

Shows insecurity, frustration and fear of failure.. Try to be happy

if you really want to know what it means, no glam or psychic readings, it means that your brain was either just entering or just leaving REM sleep, a stage in which you can have hundreds of dreams that you will not remember. But right before or right after, is where you get those dreams you remember, where your brain is bored and entertaining itself while your body is not quite at the point of total unconscious rest. You can have amazing dreams, sexual or frightening dreams, but you will never remember a boring dream. Your brain knows how to entertain itself :-)

It's kinda normal dream. Nothing to worry about.

Sounds like to me it is just a very randum dream.

you were dropping acid in your dream O.o
