Odom, wearing the incredible Kobe and Gigi tribute pendant he got as a gift earlier this year on the anniversary of the duo's tragic death, told us out at LAX this week that it actually happens "often."
"[He's] just talking to me all the time," Odom said of the dreams. "'Hang in there. Keep fighting.' A lot of s***."
LO -- who played with Kobe from 2004-2011 and stayed good friends with him in retirement -- tells us the dreams he has with the Mamba usually involve them shooting around, sometimes even in actual games.
"His spirit, it's so strong," said Odom, who also has a tattoo of Kobe on his neck. "To me, he's like not too far away. Especially when you're dreaming of someone, and they talk to you in that dream, you're definitely going to remember it."
Lamar tells us Kobe continues to inspire him to this day ... and added that the NBA legend is a big reason why he loves flying into the City of Angels.
"It's crazy," Odom said. "That's why I love coming back to L.A., too. I feel him."
