When you say it feels like you're in a fog, that does exactly mean ; Do you have scattered thoughts, mind wonders all the time, blurred visualisation during mental image projection, second thoughts about beliefs, lack or difficulty of concentration for example?
Per Ardua Ad Astra - Hail Horus!!
Me too! When I first joined spiritual Satanism I had the same thing happen! I did the dedication ritual and all was good. I was trying to get stronger though so I did trance practice. when one of my kids burst into the room during me practicing a deep trance it startled me hard and I was like... Stupid for the next four days. I was tripping over things, spilling things, and acted like i had no muscle control. I also had a super hard time getting back into any relaxed state. But today I managed to get into a deep trance and stay in it. Then slowly pull myself back out. I feel better now, im myself again. So while that might not be the exact same thing, maybe some good power meditation will help you too! Hail father Satan! And good luck.
