In the first dream with the ace of cups, you probably felt peaceful, joyful...Sometimes, we are overcome with emotion and our cup "runneth over"...We, inadvertently, project onto the cards.
The black cat symbolizes a fear of your own feminine power or intuition, perhaps, or a fear that the tarot or specific cards are associated with evil, darkness, and bad luck...that's why you maybe felt horrified to see the Devil card.
No card is inherently all good or all bad. Having an upside down dead black cat and the Devil reversed suggests these images have no power over you
unless you give it to them...
unless, you attach negative meanings to them. I think that this card and these images reflect
your fears. Maybe, you put your hand over the card because you didn't want to
face or
see something you feel has more power over you. The card can't hurt you. Maybe, it's an irrational fear and it wants you to acknowledge it. When you acknowledge it and see it for what it really is...you won't be
attached to that which you see. You'll develop objectivity. I think the cards are encouraging you to..perhaps explore your ideas, thoughts, beliefs about certain cards. Did you grow up with any specific or unique symbolism attached to the images you're seeing?
The Devil reversed, to me, also says that you want to
free yourself. That's how the subconscious is coming through. Maybe it indicates your desire to cut the
chains that bind you. That's a good sign. Sometimes, we need contrast, to see BOTH what IS good and beautiful and what is hidden from us (our
shadow self) in order to integrate different aspects of ourselves.
Shadows and Sparks go together....Darkness and Light...When you delve into the tarot or if you use it as a tool of self-discovery and personal development, you'll be required to see things about yourself, good and not so good things (which has nothing to do with "evil" per se), in order to grow and become a more balanced human being. The important part is to remember that there is always movement between moments. Nothing is static...so, all things must pass. I think you're being urged to explore with courage.
I'm a dreamer...and I often dream of cards, especially when I'm delving and exploring
...and every time I've seen a card that "troubled" me, it was because I feared what I didn't understand. When I understood, the fear left me. I was even thankful for the card that showed up because it gave me an opportunity to understand myself better.
Just my thoughts...may or may not make sense...in any case, all the best to you.
