This seems to be a common dream among our membership so, just out of curiosity, I Googled "airplane crash dream."
The first listing will take you here:
This is what they have to say:
To dream of being in this event is a feeling of not only a dramatic negative change in your life, but also to everyone around you as well as your environment. A very negative symbol and should be meditated upon. To dream of witnessing this event is symbolic of feelings of helplessness in the face of a great tragedy. In prophetic dreams this heralds a great change in the distant future (planes are associated with great distance). This change may not be negative.
Next, there's this one, which is subtitled, "Men's Dreams" (sorry ladies):
This site deals with specific dreams from people who have written them down and submitted them for analysis, but you'll find a link to their dream dictionary on the left side of the page.
If you don't care for either of these sites, you have nealy four million other hits from which to choose.
Dream analysis and symbol definitions can vary widely, depending on your source, so details are extremely important. Write down as many details of your dreams as you can remember, no matter how insignificant they might seem; if your conscious mind recalls it, it could be crucial to arriving at an accurate interpretation.
Also consider any recent major or minor life events you've experienced or are currently going through. Something as benign as an argument with a loved one can trigger a subconscious emotional response, even if you think you're okay with it.
Any problems with which you might find yourself preoccupied during your waking hours will continue to seek a solution even after you fall asleep, so it's important to relate the symbols presented in your dreams to recent real-life experiences. To dream of your teeth falling out, for instance, could simply mean that you're overdue for your bi-annual checkup, and your subconscious mind is giving you a gentle reminder of what might happen if you don't schedule an appointment with your dentist. The same dream can also indicate that you suspect someone close to you has lied to you or, conversely, that you have lied to someone you care about, and your guilt has manifested itself in your dreams. Each of the aforementioned examples would be considered valid interpretations of the same dream, depending entirely upon the dreamer's real-world circumstances.
I'm not an expert in this area (I just play one on the forum), but this airplane crash dream seems to pop up with remarkable regularity on LP.com, so it's at least feasible that it would pertain to the common enigma we're all trying to solve here.
I hope I've contributed something of value to this thread but, ultimately it's up to you to figure out how your chosen game relates to an aircraft falling out of the sky.
