The literal meaning of 'Schatten' (shadow) refers to the absence of light. All other meanings are metaphorical and are usually part of fixed idioms that you should learn as a whole.

The cat is sleeping in the shadow under the car.
Pay attention to the case after the preposition 'in'. 'Im Schatten' (in the shadow; dative) describes a location, while 'in den Schatten' (into the shadow; accusative) describes movement.

With his new record, he outshone all the other runners.
The idiom 'über seinen Schatten springen' (to jump over one's shadow) means to overcome one's own fear or pride. The possessive pronoun ('seinen') changes according to the person.

I had to overcome myself and apologize.
light
'das Licht' and 'der Schatten' are clear opposites. 'Licht' is the brightness that allows you to see. 'Schatten' is created where an object blocks the light and it becomes darker. The two words often belong together, especially with sun, lamps, or photos. When something is bright, you speak of 'Licht'. When a dark area is created by an obstacle, you speak of 'Schatten'.
