Cannot find my data in lost+found folder in home folder

Cannot find my data in lost+found folder in home folder

I am using Ubuntu 12.0. I kept all my data in lost+found folder in home
folder. If I open this folder, it is coming that I do not have permission
to open this folder. Here are the commands I am getting:
srujana@srujana-desktop:/home$ ls -l /home
total 20
drwx------ 2 srujana srujana 16384 Jul 22 00:40 lost+found
drwxr-xr-x 32 srujana srujana 4096 Sep 28 17:43 srujana
I don't understand where has all my data gone.
Please help me... Thank you.
