stuck at the very beginning

[d0m]

hey guys,

i'm stuck where you get back at the beginning of the game.
i cant open the small door, so i tried to go through the bull's eye,
where i have entered the ship in the dream sequence before.
but when i go through, i always fall down and have to reload
the last saved position. i thought i have to jump onto that platform
infront of the bull's eye. but i cant even jump...

please help me out

greets
