Ctrl+Arrows work differently in normal mode and in insert mode

Question

For some reason, in my VIM there is a difference in behaviour of Ctrl+Arrow keys in normal mode and in insert mode. To demonstrate this, I edit the file which contents are:

aaa.aaa,aaa/aaa!aaa@aaa#aaa$aaa%aaa^aaa&aaa aaa*aaa(aaa)aaa{aaa}aaa[aaa]aaa-aaa=aaa_aaa"aaa'aaa

In insert mode, when I press Ctrl+Right key, here is where the cursor stops:

aaa.aaa,aaa/aaa!aaa@aaa#aaa$aaa%aaa^aaa&aaa aaa*aaa(aaa)aaa{aaa}aaa[aaa]aaa-aaa=aaa_aaa"aaa'aaa

In normal mode, here is where the cursor stops:

aaa.aaa,aaa/aaa!aaa@aaa#aaa$aaa%aaa^aaa&aaa aaa*aaa(aaa)aaa{aaa}aaa[aaa]aaa-aaa=aaa_aaa"aaa'aaa

I'd like to make it work in normal mode just like it currently works in insert mode.

What I know so far is that :map and :map! don't contain any maps for Ctrl+Arrows keys. Also, VIM recognises Ctrl+Arrows sequences right, i checked that by doing

:nmap <C-Right> :echo 'Normal mode Ctrl+Right'<CR>
:imap <C-Right> <ESC>:echo 'Insert mode Ctrl+Right'<CR>

And I see the effect when I try pressing Ctrl+Arrows How can I fix this?

Update: I've tried the same with a new user who has no ~/.vimrc or ~/.vim, and it reproduces Update2: I'm not remapping the key either

OK looks like @ChristianBrabandt is right. The answer is,

:nmap <C-Left> b
:nmap <C-Right> w
