Me and my friend were messing about during a lightening storm outside and offered ourselves to Zeus(like him to take us bc we are stupid). Since then when we have been together we have had 4 near death experiences in the past 2 days. Could this be connected? Can we do anything to stop this?
The four near death experience may be something you are looking too deeply at.Zeus and many other Gods and Goddess, often prefer their followers to be alive. In saying so be careful and mindful of your actions so you are not put into so many near death experience.
I definitely would not agree that you should "summon" Zeus, summoning deities is generally accepted to be pretty disrespectful.
As others have said, I doubt Zeus was trying to kill you. A protection spell could be in order, unless a particular thing is causing these experiences (ie, if someone is trying to hurt you then call the police). If you feel Zeus is now present in your life, you could reach out to him respectfully and explain the situation, perhaps with an apology for joking around with a deity if you feel the need.
At best, Zeus might have been offended or amused and is teaching you a lesson, but God's don't typically kill people these days. I would apologize to him.
You can't sacrifice a goat, but I would look up what offering he likes and give him that. Perhaps make some nice Greek food and leave it outside as a way to say sorry. If you're serious about working with him, you can set up an altar, pray to him, say blessings before meals to him, and hold ritual calling on him. Overall, he's not trying to kill you, probably just scare you until you wise up. Once you apologize, it should stop.
