Reality sets symptoms and conditions

I've been trying to cut down on my celexa ( although i take the generic citalopram 40 mg) I found that if i came off it too quickly without decreasing the dose in stages (i had tried cutting down to 20mg) my head would become extremely fuzzy, whenever i turned my head or moved it it would feel all tingly and disoriented. I also found it was very hard to concentrate. now that I'm gradually getting off of it i notice that my dreams are very real and vivid and i can no longer tell my dreams from reality. I wake up confused not knowing where or who i am until reality sets in. I was hoping to get off citalopram completely due to the fact that it is not recommended to use when you are considering becoming pregnant due to the impact on the fetus. however, i found that without it i'm very spacey and find it hard to concentrate. I don't know if thats another side effector if thats my anxiety coming back from not taking it...
