Do you ever feel that there are certain situations that you just can't read? That is, every time you ask a question relating to a certain situation, your reading just doesn't make sense, or two readings asking different questions about the same situation or person will yield conflicting answers?
It's as if the cards are trying to tell you: Don't ask questions about this situation.
Does this ever happen to anyone, or do I just think it's happening to me because I'm a new/unskilled reader?
As a new/unskilled reader, I can answer your question, I think.
See, I have trouble reading a lot of times because, since I'm new, I constantly doubt my ability to read things correctly, and usually do multiple reads if I don't understand it the 1st time...rewording my question, or attempting a different spread. Experienced readers will generally tell you not to do this, but to instead focus on the cards, where they are in relation to the others, etc..., and more feel than look for a concrete meaning.
I have a little chart I keep for reference to what the cards generally mean, and I've immediately come to find relying on it to understand is almost a joke at times, especially for more difficult reads, simply because the answer will almost never be as concrete as what's written on a paper. Don't get me wrong, the chart IS helpful, but nothing you can read physically about the cards are going to tell you a meaning 100% accurately in this: they point, but they don't tell.
I've also come to find that when you read yourself, it is VERY important to finish the spread BEFORE you start trying to gather a meaning. Trying to understand things and read as you go will more than likely throw off your results, though not always. To steal a few words from the big screens:
"Every time you look at the future, it changes...because you looked at it."
This is why I will take the time to point out that on here, I've seen a lot of far more experienced readers say 'I don't believe in predictive tarot'...because I feel like when you look and attempt to use the messages you see to make changes to yours or someone else's future, or when you're trying to dissect your reading as you lay down each card to look for a meaning as you read yourself, that the future has already changed. I can't speak for them if anything like this is their reason, but that's my best reference as to why it's difficult sometimes.
I can't say for sure if there are or are not situations that can't be read, but I can say for sure that there are situations where you won't be able to get a good reading. I'm not going to limit myself to just those two examples: Environmental factors such as trying to read in a busy place or trying to read in a place that has a lot of stray energy may throw it off or make it harder to read [that's why most readings are private and in a clean, blessed space]. Emotions [yours or the person's you're reading] can throw the read off, especially strong ones, and even more especially strong, negative ones. Lastly, spirits have been known to cause issues with reads too (I've read posts about people seeing them during their reads due to their intense focus, and though it hasn't actually happened to me, I'm sure they truly can be distracting, even if they're not malevolent ones, because you'd probably not be used to seeing them and their presence will break your focus)
I will also say it's good to have something like selenite [a cleansing stone] on your person and candles [most of the few experienced readers I know use white candles because white is a cleansing energy, but I've been favoring purple ones lately...if you believe in this, purple represents the crown chakra and is supposed to help you focus on divinity/the universe better. It's also the highest vibration the humans can see with the naked eye, and higher vibrations are supposedly better vibrations...I'll get into this part privately if it's piquing an interest, cause I digress right now] and, if you're still doubting the area, a prayer [I'm not an atheist, but my view of religion is...complicated, so usually I go with my next method if I'm still holding doubts after the candle lighting] or to burn some white sage or cedarwood to cleanse the space further
If anyone contradicts what I've written, they're likely correct, as I'm also new, but I hope this turns out to be more helpful than confusing, at the very least. That being said, that's about all I've got. Good luck!
