"don't let the sound of your own wheels drive you crazy
I have had similar experiences with some tarot decks. I used to put decks under my pillow too. I no longer do this. The DM does not frighten me at all, in fact I find it amusing but very accurate. I got rid of the Konoxi cards(spelling) b/c they disturbed me a lot. This may be due to the fact I do believe that evil spirit entities do exist . the Geiger deck is frightening to me as a woman as I have experienced sexual assault and thus it just horrifies me. I had an experience with the Thoth deck that I will not put on a Internet board. The deck is not scary but the author is. ( to me anyhow).
Was your deck new or used? I have gotten some decks that came to me with negative energy. I know they are just cards, but the energy was just bad. Other decks I have opened up and they were just delightful." waking the wild spirit" by Poppy Palin a delightful deck that feels so fun and happy.
Soooo. for whatever reason this decks scares you. The Dark Grimore scares me too. I can't explain exactly why but it is just a bit frightening. There are things you can do if you feel very frightened. Sage the house and I have used the Lesser Banishing spell. It is a very nice ritual that seems to protect you from negative energy . You can find it all over the net and I'm sure it is on this site too. here is just one Link, I don't know anything about this site it is just the first one that came up.

The Eagles had a song a long time ago and a line in it went " Take it easy"
" don't let the sound of your own wheels drive you crazy...".
for fun here are the lyrics
Take It easy, take it easy
Don't let the sound of your own wheels
drive you crazy
Lighten up while you still can
don't even try to understand
Just find a place to make your stand
and take it easy
