The whole GTA fandom has been insane over a myth in GTA V. In Grove Street, behind a house, next to what would be Ryder's, there is a letter scrap. Picking it up says
"1/50 Letter Scraps Found. Find all 50 to Solve Lenora Johnson's Murder"
This has made people believe that CJ's mom and her ghost appear in GTA V. However, Lenora Johnson is just an easter egg referencing the girl with the same name, who voiced Beverly (CJ's mom) in the Introduction. Also, CJ's mom's name if Beverly, not Lenora.
It's still interesting how Rockstar chose her last name as Johnson, as if they are referencing the Johnson family from GTA San Andreas. Even though, Lenora johnson is definitely not related to Carl Johnson.
Either way, it has been proven that GTA San Andreas is not in the same fictional universe as GTA V, so the Grove Street in GTA V is not the same as the one in GTA SA. However the Niko Bellic reference mentioned by lester is 100% true because GTA IV and GTA V are in the same universe.
There's also a Lenora Johnson letter confession at the top of the mountain with the cable car, I think it's mount Chiliad, unsure about the other 48.
[story mission spolier ahead] when I arrived at Grove street with Trevor and Lamar I was so excited/curious to what it would be like, the nostalgia and resemblence was strong but I was very sad to notice it had been took over by the ballas.
Lamar, at one early point in the game, mentions that Grove street used to be run by families and it's slighly sad that it's been took over but then he also suggests that Grove Street Families are probably living it large in SUV's by now ... which is probably true since on the San Andreas game CJ ends up owning a lot of mansions, money and luxorious buisiness'.
GTA San Andreas and GTA V are two different universes however the references inbetween have obviously been made by rockster as a definite link between both games ... maybe to spark up discussions like these by fans like us.
An unrelated note; the background to this site is a little scary and might have the potential to be involved in my nightmares. It's very powerful.

Her last name is Johnson, because of Beverly's voice actor. Look at the GTA SA voice cast if you don't believe me. Beverly's actor's name is Lenora.
