The beloved actress joined us Wednesday on "TMZ Live" and recounted her frightening tumble in Africa, but told us she prefers to focus on the incredible steps she took to get back up on her feet again.

Lewis said she walked out onto a deck at her luxurious accommodation on the Serengeti of Tanzania -- she says it was pitch black outside, so she never saw a huge gap in the deck between her and the infinity pool. Suddenly, she plummeted down 10 feet and slammed to the ground.

Jenifer was unable to move and had to scream for her travel companion to come to her aid, and call for medical assistance ... which took a long time. She told us, while she was down there she had some scary encounters with wild animals, before a Doctors Without Borders team airlifted her to Nairobi, Kenya.

JL says she suffered through a 9-hour surgery before spending the next 6 days in the ICU ... and then she had to start a long stretch in a hospital bed.

She's got a ton of kind words for the people who took care of her when she couldn't walk or go to the bathroom by herself.

As for why she's sharing her story now ... Jenifer wanted to tell people she'd fallen once she could also tell the world how she'd gotten back up -- an inspiring message no doubt.

Jeni was on the verge of tears as she recalled her ordeal, but soldiered through the convo, displaying the kind of strength that got her back to her feet.
