yeah its nice to have beautiful dreams, I,ve not had a bad one in a while, i find the bad dreams induce lucidity really easily as long as you face the fear you can make the fearful experience into a very beautiful one, are you scared of spiders by any chance, if so its probably a survival mechanism so you can face the danger of a spider in the dreamworld as practice incase of it being a reality one day, i believe dreams are useful in more ways than one, a perfect training ground, and a perfect look into the subconscious mind ive found allot about myself through my dreams and become very centered and balanced, it took me a while but when I got into it more deeply i realized dreaming was the perfect way to heal yourself even energetically you can heal yourself with reiki and the likes dreaming is awesome........
Interesting dream. It's nice you got to have such a wonderful one. Just last night I had one with a spider that I really felt crawl on my back and stick its spidery claws into my skin. It wasn't nearly as pleasant as what you seem to have experienced.
