"Ok Vistaril dreams - hydroxyzine vivid dreams do exist.  What I am sure of is this:  When my life was going great, the dreams were awesome!  So Vistaril (hydroxyzine) dreams were WONDERFUL and I have dreamed very vivid beautiful beach sunsets I have never really seen before-with flowing water seemingly from the heavens and beautiful colors I have never seen before.  I looked forward to my Vistaril (hydroxyzine) dreams!  

BUT when I became stressed with the death of a friend or argument with co-worker or anything negative that day-then came the VIVID Vistaril nightmares began. So wild,so vivid, I was THRILLED to wake up and find they were not true because they were upsetting.  State of mind is important I feel."
