The 9 of Swords clearly indicates that you are worried (having nightmares) about something. What I’ve learned is that if the card is right side up, it indicates that you are keeping yourself awake thinking about things. For some, you may actually be worried sick!
Are you feeling inadequate? Are you reliving the way you handled something thinking you came up short? Or are your worst fears concerned with the actions or inactions of someone else? Who are you worried about (or for)?
Often our worst fears manifest in our dreams. Don’t spend all your energy worried about “what ifs” that may never happen. Deal with life as it occurs – it’s often not as serious as you fear it will be. Remember that swords represent the element of air. That governs thinking and communication. Don’t overthink it. Use your fantastic intellect to weigh your options, and allow them to play out naturally.
