anxiety
"Worst medication experience! I was prescribed this drug for a panic attack that would subside. The pill was hydroxyzine 25 mg.. I took half of it as I'm leery of side effects to medication. It first felt like everything was okay. 
I went to sleep and it all started there. I had some of the vivid dreams. I would luckily be awakened by my surroundings. I would then get in bed and lay there. I felt paralyzed. Like my brain couldn't make my body do anything like raise my arm. I hallucinated and heard voices. I decided I couldn't go back to sleep after that. I woke up but felt as I was floating. I remember trying to focus but was looking for imaginary things. It literally felt like I was dreaming while awake. It was terrifying. Do not recommend!"
