Dimension X

A few years ago, I had a dream I was standing in the street... I got randomly hit by a speeding vehicle, but instead of getting splattered on the pavement or waking up, I was launched into the air, still in standing position, (here's where I become semi-lucid) then I notice how far I am from the ground, (actually about triple the height of telephone poles), but instead of freaking out, I just crossed my arms and said "Is this really supposed to scare me?" Just after I said that, everything turned distorted, like it was television, and someone was messing with the antenna. Then everything went dark for a few seconds, and I woke up. Before I had that dream, I was terrified of heights. Now... They don't bother me in the least. Has anyone else had this sort of experience? Like, gotten over a fear in a dream?
