Low flying dreams

The Flight 370 story, with the parts about it flying low during certain sections, either deliberately or accidentally, reminds me about the recurring "low flying" dreams that I have had in recent years.

Although it seems a while since I had one, I have over the past years had dreams in which I am on a passenger jet, looking out the window and realizing we are flying really low for no apparent reason.   Sort of so low we are going up and down to get over hills.  No one else on the plane seems to have noticed.  I find it scary.

I have not been able to identify why this should be a recurring theme in my dreams.  I was interested to see in New Zealand a few years ago a smallish passenger jet flying through a valley on the approach to Queenstown airport.  I thought I wouldn't like the look of that if I were in the plane.  But was that enough to bring on a recurring dream?  I also think I might have had my first "low flying dream" before then.  They have turned up now and again for quite a long time.

That is all.
