Usage tips
Word formation
The word 'psyche' is a special form in which the noun 'die Psyche' (the psyche) is used directly as an invariable adjective. It is not declined, so it is not adjusted to the noun.
EXAMPLE
Das war ein total psyche Erlebnis.
That was a totally psyche experience.
Register: colloquial
This use as an adjective is very rare and clearly belongs to colloquial language, often in a young or creative way of speaking. It practically never appears in formal texts.
EXAMPLE
Die Atmosphäre auf dem Festival war irgendwie psyche.
The atmosphere at the festival was somehow psyche.
Sentence position
As an adjective, 'psyche' is almost only used predicatively, after verbs like 'sein' (to be), 'wirken' (to seem), or 'finden' (to find), or as an adverb. Use directly before a noun is extremely rare.
EXAMPLE
Ich finde seine Kunst total psyche.
I find his art totally psyche.

Psyche vs körperlich
physical
'körperlich' refers to the body. 'die Psyche' is actually a noun and means a person's mental, emotional, or psychological side. In very rare, creative forms it can be used like an adjective, but in normal German you would more likely say 'psychisch' or 'seelisch'. So the contrast is: the body on one side, the psyche or inner state on the other. For learners, the important point is: 'körperlich' is a normal adjective, while 'die Psyche' is normally used as a noun.
