Amanda Bynes is back. And she may be of the undead.

The troubled actress was spotted about 1:45 Friday morning, alone, at New York hotspot SL, sources told E! News.

"She was alone, definitely like ... walking into people, she looked just zoned out of her mind and randomly dancing with some guy," said the eyewitness.

Did she chomp on him? That would explain a lot.

"We were, like, 'Can we get a picture of you? You're Amanda Bynes?'" said the source. "And she said, 'No, I'm not and I don't want my picture taken.'"

The weird part was that she said it in Romanian.

Bynes supposedly continued to walk around before leaving with some people she had just met.

Sensible. She obviously needed to feed the rest of the pack.

"We wanted to go to Avenue after SL, so we walked there," the source said. "On our walk, we saw her again with those people, just stumbling. I felt so bad for her. I've never seen anyone like that, zoned out. So we walked into Avenue and I just saw her walk into (popular hangout) Artichoke. She just sat in a booth by herself and that was the end of that."
