extra .. folder in /dev

Help (if it is not too much trouble).

I have a Linux machine that has been recently
rooted. I have found many strange things on the
hard drive of the server. when doing an 'ls -la' 
in the /dev folder I see the following:

drwxr-xr-x   7 root     root        34816 Sep  1 14:27 .
drwxr-xr-x  20 root     root         1024 Sep  1 14:34 ..
drwxr-xr-x   3 root     root         1024 Jul 15 11:22 ..
-rwxr-xr-x   1 root     root        26450 Apr 17  1999 MAKEDEV
-rwxr-xr-x   1 root     root         1598 Apr 19  1999 MAKEDEV.ibcs
lrwxrwxrwx   1 root     root            4 Jun 11  1999 X0R -> null
lrwxrwxrwx   1 root     root            8 Jun 11  1999 arp -> inet/arp
crw-rw-r--   1 root     root      10,   3 May  5  1998 atibm
crw-r--r--   1 root     sys       14,   4 Apr 17  1999 audio

Why is there an extra '..'? There was also a 
'...', but I have deleted it. How should I go
about deleting the extra '..'? I am kinda new, 
so any help is appreciated, I can post any other 
information needed.

Thanks
