gio,
Looking at my analysis of your one inch steel wire in my left leg a possible interpretation of the spoder in your dream might be:

To see a spider in your dream indicates that you are feeling like an outsider in some situation. Or perhaps you want to keep your distance and stay away from an alluring and tempting situation. The spider is also symbolic of feminine power or an overbearing mother figure in your life. Alternatively, a spider refers to a powerful force protecting you against your self-destructive behavior. If you kill a spider in your dream, then it symbolizes misfortune and bad luck. To see a dead spider in your dream implies that you have overcome some strong feminine temptation.

With that the caterpillar {which is a common dream image} would represent;

To see a caterpillar in your dream signifies a stage in your own personal growth and development where you are on your way, but have not yet reached your goal.

Put this with the other dream and see where it might fit}.

As an experienced dream analyst {27 years} I can only provide an outline of the emotional energies from a dream with the limited personal knowledge about the dreamer, including recent emotional charged experiences which all dreams focus on {along with the foundations, early life programming, for the dreamer's personality, attitudes, traits, actions and reactions}. I know your age, gender and English is not your first language.

Dreams are about emotional energies and have a primary language of symbol and metaphor {with some literal applications being exposed}. The interpretation of the images from your dream are Jungian in nature {scientific}.
