Dream Analysis

For the record, I rarely remember any of my dreams, but last night was a strange one. Possibly brought on by daylight savings time messing with my sleep schedule, possibly not. But I now find myself in need of some analysis, and so I'm calling on all of the dream experts out there.

This dream took place at my grandparents house. They have been dead for several years and the house is long sold, so I'm not sure why I was there. I was sitting on the front porch with someone, I don't remember who, when I looked up in the south western sky and saw a low flying stealth bomber. The plane made an attempt to circle around before crashing into the house across the street. I ran inside to tell someone they had to come out and take a look at it, and when I got outside, it had shrunk down to about the size of a car. Flames and smoke still coming out of it, a hatch opened, and an alien came running down the ramp from the hatch. This particular alien looked just like a spider, and when it saw me, ran full speed straight at me, jumped and landed square on my face. Naturally I began frantically swatting it away, and even after I was sure it wasn't on my face anymore, kept wiping my face. That's when I woke up.

So is this some kind of fear of aliens? Fear of spiders? Fear of stealth bombers? Fear of something else? What can it all mean? Or does it not mean anything? Do all dreams have meanings, or are some just weird dreams. Come to think of it, I did watch Spiderman 3 the night before. Perhaps that had something to do with it.
