She chuckled: "Thought I had an ulcer, but it turns out it was a fulcer.'"           

Once she was there, the Oscar winner underwent an endoscopy procedure. "I just did this thing yesterday called an endoscopo-something, where they put you to sleep," she revealed. "And the woman - it's pretty clear when you first meet me, I'm a freakin' head case and I'm crazy - so I'm in there like, 'Ugh, what are these?! What do they mean?! What does that say?!'"

When the anesthesiologist went to work, she recalled, "The last thing I said was, 'I'm paralyzed!'"

While under Lawrence experienced some weird dreams, "I dreamed there was a nuclear bomb that went off...And the first lucid conversation I remember having was about the Kardashians!"

Here's some background about endoscopy procedure which the X-men star experienced.

According to Web MD, endoscopy is a nonsurgical procedure that is used in order to examine the digestive tract of an individual. The procedure requires an endoscope, which is a flexible tube with a light and camera attached to it. The endoscope will be inserted so that the doctor can view pictures of the individual's digestive tract on a colored monitor.
