I think the fact that so many people are taking a highly metaphorical dream and interpreting it literally ("Buy a new gun if you don't trust your Glock!") is an interesting discussion on THEIR psychology.
If a person's trust in a firearm is fundamentally shaken and can't be restored (whether the reason for the distrust is logical or not), changing guns is a reasonable option. <=== and this says NOTHING about MY psychology.
How a person interprets something, whether logical or not, is highly personal. It makes no difference that a fear or phobia is illogical. The OP could spend hundreds or thousands of dollars on a psychologist, and never solve anything. Or he could sell is glock and buy something else A LOT CHEAPER than several psycholist's visits. Of course, I have to wonder what happens after his NEXT dream, but that is another story. The only thing that says about MY psychology is that I am practical and frugal.
