I was under the impression that spiders and, more specifically or intensely, webs meant sexual repression of some sort. That is in a dream.
A friend who is a psychologist and writer used to, in his early years, dabble a lot with dream interpretation. Now he considers it somewhat bunk. But that was the going wisdom he passed to me.
It was wild, as at these few times (long moments peppered) in my life that I would try to be straight, not simply date girls (which I did every now and then with confidence at other times as well), but deny my attraction to men, I would have these vivid dreams of spiders.
For a few years I lived in Southeast Asia and would spend hours and days in the jungle walking or bike riding where possible. There were two kinds of spiders that caught my imagination, one as big as a man's hand with fingers outstretched, and the other about 3 or 4 centimeters long.
The first would weave elaborate webs right at my face level above paths in the jungle. They were vibrant in color, bright red, orange, green, blue, all adding up to whatever the color of cold fear is. I never walked into their webs but time and time and time again would look up to see one a couple centimeters from my face as I was about to.
The others were worse. They lived in or around homes and literally would chase you. I'm not joking. They didn't build webs, their sole purpose in life was to terrorize the shit out of you.
The last throes of any attempt to pretend or demonize my sexuality happened at this time, and these creatures lent powerful images to my dreams. I woke up in sweat.
