HI!

I'm not sure exactly what your dream means, but it kinda reminded me of dreams I used to have about elevators.
Seems whenever I got in one in a dream something would go wrong. Since I have no fear of elevators, I looked at the setting of the dream: I get into a box, and lose control.
Turns out this dream was related to a compulsive behavior/habit that made me FEEL totally out of control.

So lets look at your dream:
It seems like you're moving really fast, yet you can't see where you're going.

Are you an action orientated person?
Do you fill your life/time with a lot of activities?
Are you constantly running around doing things?

You say you wake up feeling sick.
Is it a motion-sickness?
Is there anything else in your life that makes you feel this same way?

I hope this helps you.

Colours represent the idea of emotions. Your dream seems to suggest that you are being overwhelmed by emotions, to the extent that you could see yourself becoming ‘sick and tired’ of all these feelings – at least when you think about this issue when wide awake (i wake up feeling sick) and thinking with full awareness.

Another point the dream can be suggesting is that you might have the impression that you are actually reeally getting somewhere in life (like im moving reeally fast) when experiencing so many emotions. However, the end result (feeling sick) does not imply a beneficial result.

Another point this scene can be bringing out relates to the colours being like a blur of colours. This can indicate that your feelings are not very distinct, they are not clear or certain. You may be blurring the line between feelings. This can happen when you do not take the time to focus on any one feeling to allow you to distinguish one feeling from another properly. Notice the impression of moving fast which suggests little time to actually see one of the colours clearly.
