Walked into the bedroom to put away some laundry, and what was laying on the floor next to the bed? The King of Swords, looking right up at me with his sword in one hand and his other raised in a warding-off gesture. The best I can come up with is someone planning my husband harm (it was on his side)
Kind of an odd interpetation for a fallen card. Off hand, I supsect all it simply means is you need to talk to your husband in bed tonight. He's got a lot on his mind, is having trouble making a judgement, and would probably have a clearer mind if he could just talk things out with someone--namely you.
But if you're really worried then do a reading. Take the King/Sword and put him out on the table. Shuffle the deck and lay five cards around the King/Swords--the question you are asking is "How does this card relate to":
1) Husband's communications, information, mental state (lay card down to the left)
2) Your husband's energy, career or goals (lay card up above King/Swords)
3) Love, family, home (Lay card to the right)
4) Your husband's physical well being, finances, job (Set card below King/Swords)
5) Advice on how to proceed: lay card over King/Swords
You seem to be reading King/Swords as "general" harm to your husband, but it's the King/Swords. That limits the type of harm to harm from from a bad judgement (either his or someone else's). Either that or he's going to come down with the flu
Doing a clarification reading like this will help you specify where the harm is coming from or going to, and make things better.
