TMZ After Dark' Tour Chanel West Coast Points Out Haunted Former Home ... Ray J Gobbles Up Cookies!!!

 Chanel West Coast and Ray J seemed ready to gather round a campfire this weekend ... 'cause he gobbled up snacks, and she told ghost stories on our "TMZ After Dark Tour."

The two stars hosted the Hollywood tour on Friday and Saturday nights, respectively ... and, Chanel got the group into spooky season early when they drove past her old apartment building in the City of Angels.

Chanel swears it's haunted ... and, she got out of there as quick as she could back in the day! 

While riders got the usual fun-filled tour -- with drinks, dancing and good vibes all around -- they also stopped by Crumbl ... a popular dessert shop that

celebrated its eighth birthday this month!

Ray J hopped off the bus to get his cookies from the national chain -- which boasts more than 1,100 locations -- and he tried out the Milk Chocolate Chip Cookie, the Original Pink Sugar Cookie, and the Cornbread Cookie off the Secret Menu ... and he crushed these cookies FAST!

Either way he -- and everyone else on the bus -- loved their cookies ... and, if you wanna take part in an experience like this, get your tickets now 'cause they go quicker than Ray J eatin' desserts!
