Dream interpretation

OK I have to admit this is really stupid. I bought an app on iPhone (actually I bought 2! One in Chn, one Eng) on dream interpretation. I prefer the one in Chn. The one in Eng is too....wishy washy.

I had quite a few vivid dreams lately. Here's apparently what they meant:
1. Plane crash into tunnel - which apparently is a sign of lack of confidence, and my distrust of people around me
2. Listen to someone presenting in a meeting - which means I will have chance to attend international conferences (?!)
3. Accident/adjustment in office - which means I long for better performance at work
4. A friend crying - which means the friend will forget about me

Um....
