explanation of to stay

i, too, had a dream last night

in it i fell fell like in every other night
the scenery changes sometimes the temperature
but i was fallling falling like always last night
and i passed by a new scene called LIGHT
it touched me for the split second it lasted
it lifted me it shocked me it freed me
i managed to snap my arm out and tear a slice
and i tasted the LIGHT and it was so tempting
it was so good i wanted more i had to have more
i was falling further and further away and i needed
i needed i needed and i had wanted for so long
the LIGHT
but i was scared, i was shocked, this was finding what i lost
i wasn't ready was i not? i was tempted so i stopped
i let the scene pass me by so i could have some time
time to think time to think and decide what to do
about this scene that caressed me, what to do about
the LIGHT
i waited half a day and opened my eyes to see that i was still falling
falling again like always and i could barely see the light and it
it was leaving me? it was floating higher as i fell it was shrinking
becoming just as dark as what lay below me
so i stretched out my arm. i stretched it for inches and feet and miles and days
and i stretched it for three months exactly
and i grabbed hold of the light and pulled it into my heart
and i loosened my grip
and it stayed close to me and i knew it meant it
and i held the light like i hold a lover
like one holds a dream in the morning
like one holds infinity in the afternoon
like a teacher holds a book
like a student holds the first lesson he ever learned
i held the light like i hold a lover

and when i woke up
she kissed me softly on the lips
