Astral projection?

I signed up to go back to school, but ended up picking the wrong course.

The course was about brains and pyramids!
The guy in charge said if we wanted to do this course, we had to go up in one of those devices that hydro guys go up in to fix power poles.

We went zooming up at a very high rate of speed, plus to about as high as a very large ferris wheel.
It almost took my breath away.
We finally came down to the ground,was i ever glad.
I felt i needed to get out of this course b/c i did not want to face having to go that high again in the air to do this course.

Do you think this is still a fear i am facing?

Maybe i am not ready for this step that seems so monumental, but then if i wasn't i wouldn't be given these dreams to forge ahead.
Could be preperation time for a major change...

Any ideas.

I also dreamt about rain last week as well and about chimneys.

Thanks
