Lamar Odom is clearly not over Khloe Kardashian ... the ex-NBA star recently said that he misses his ex-wife "so much" -- and is still dreaming about her.
"Celebrity Big Brother" cameras captured Odom's revelation while he was making his bed on the show ... with Lamar repeatedly telling his housemate, choreographer Todrick Hal, that he thinks about Khloe often.
"I had some good dreams last night," Odom can be heard telling Hal in the footage. "I dreamt about my ex-wife last night."
"I miss her so much," Odom continued.
