I have both of these...and they are both wonderful oracles for use.
the Dream cards are especially nice for completely intuitive ramblings!
They seem to work the same way that the symbols in dreams do...they can be intensely personal. I have the Metamorphisis tarot by the same artist...and the two decks work great in tandem.
The Psycards are one of my favorite oracles to mix up with others too...they just have nice archetypal symbols, and I love to use them for events.
They live in the same bag as my Madame Endora cards...and I often read them together.
Have fun with your new treats!
