Experiencing 'proof'

[Darkstar]

I have to admit that at first, I think Drich really fucked with my mind.

Expirience translates to Erfahrung - which is more a technical and scientific term in our language.

No one here would actualy call a dream a "expirience" since expirience\Erfahrung is a term reserved for "expiriences" out which one has learned lessons.
One is a good engeneer because of long time work expirience. for example.

Or is the use of the term "expirience" the same in english and Drich is the one whos mind is fucked?

It can mean both. An experience would be like something that happened to you, whereas experience would be having many experiences with a certain thing and thus becoming knowledgeable about it. Here:

ex·pe·ri·ence (k-spîr-ns)
n.
1. The apprehension of an object, thought, or emotion through the senses or mind: a child's first experience of snow.
2.
a. Active participation in events or activities, leading to the accumulation of knowledge or skill: a lesson taught by experience; a carpenter with experience in roof repair.
b. The knowledge or skill so derived.
3.
a. An event or a series of events participated in or lived through.
b. The totality of such events in the past of an individual or group.

Drich is clearly referring to definition 1.
