A woman who lived 130 days alone in a sealed cave with no human contact climbed out today, waved to a crowd of about 60 people and said, ''Wow, man!''

Stefania Follini poked her head out of the entrance to the cave and put sunglasses on over her regular glasses to reduce the glare of the bright midday sun. The temperature was 97 degrees, a big difference from the cave's constant 74 degrees.

The 27-year-old Italian interior decorator volunteered for the isolation experiment, which began Jan. 13, to help researchers learn how people could be affected by the long solitude of interplanetary travel.

Miss Follini had taken English primers into the cave, and she had apparently learned some of the language in her isolation. She told the crowd, ''I feel great,'' then nodded when asked if she would do it again and said, ''Sure.'' 'Are You Really Serious?'
