Cool site - I bookmarked it - learning more German one word at a time - great word btw
The word has a funny history. It is an example of how inventions in advertising language based on humour can become 'real' offical language and so even entering the dictionary although it is actually a wrong grammar word - a fact which made it sound so funny even for Germans.

I remember the original ad campaign back then. It was for coke and their new (indestructible = unkapputbare) PET bottles. Btw, the speaker in that ad was the same dubbing actor (or one of them) who spoke as Captain Picard of TNG for the German language version, that is why'unkaputtbar' also stuck with me because of his remarkable voice back then.
Except this one is in reverse as he slams back in.
I once slammed 'back in' from my mental body from a higher plane to the astral body. That was heavy because I was not used to it, it seems. So I 'felt' the impact in my astral body, which is strange as usually you don't have these kinds of sensations in your astral body. I mean you can feel pain or taste or whatever if you activate that sense, but it is a rare case.
I also know a feeling when you re-integrate the astral/etheric into the physical body. In my case it is an electric feeling similar to goosebumps. On my lucidiary I called it REES back then (Re-Entry Electrical Sensations), they are not to be confused with the 'vibrations' which are normally exit-related. Yeah, I created lots of acronyms back then, almost making it sound a bit scientific,
cool times they were.
