I notice that in
/usr/share/wordlists in Kali Linux (former Backtrack) there are some lists. Are they used to bruteforce something? Is there specific list for specific kind of attacks?

Kali linux is a distribution designed for penetration testing and computer forensics, both which involve password cracking. So you are right in thinking that word lists are involved in password cracking, however it's not brute force.
Brute force attacks try every combination of characters in order to find a password, while word lists are used in dictionary based attacks. Many people base their password on dictionary words, and word lists are used to supply the material for dictionary attacks. The reason you want to use dictionary attacks is that they are much faster than brute force attacks. If you have many passwords and you only want to crack one or two then this method can yield quick results, especially if the password hashes are from places where strong passwords are not enforced.
Typical tools for password cracking (John the Ripper, ophtcrack, hashcat, etc) can do several types of attacks including:
Rules attacks are likely the best bang for the buck if all you have are standard computing resources, although if you have GPUs available brute-force attacks can be made viable as long as the passwords aren't too long. It depends on the password length, hashing/salting used, and how much computing power you have at your disposal. Kendrick lamar good kid maad city itunes.

One of the better basic wordlists in Kali is
/usr/share/wordlists/rockyou.txt.gz . To unzip simply run gzip -d /usr/share/wordlists/rockyou.txt.gz .
Be sure to add 'known weak' passwords that are used by the organization you are testing. I like to add these 'additional' custom passwords to the top so they are tested first.

Those lists can be used to feed into several programs. So for instance
aircrack-ng has an option -w where it takes a wordlist as argument. The password testing program John the Ripper also takes wordlists to accelerate the guessing.

In addition to what's already mentioned here, the wordlists are used in conjunction with some of the web app tools and things such as sqlmap. If you're looking for places to use them, download some of the 'boot to root' VMs like Kioptrix and De-ICE and have a go at brute-ing some passwords.
As for specific lists for specific types of hacks - not really. Unless you're doing something targeted against a person you know some facts about (in which case you'll use something like CUPP - Common User Passwords Profiler - to generate a custom wordlist for that particular target).

I’m wondering where I can find good collections of dictionaries which can be used for dictionary attacks?
I've found some through Google, but I’m interested in hearing about where you get your dictionaries from.

Nice list collected by Ron Bowes you can find here:
http://www.skullsecurity.org/wiki/index.php/Passwords.
Other list is from InsidePro:

An important one that hasn't been added to the list is the crackstation wordlist
The list contains every wordlist, dictionary, and password database leak that I could find on the internet (and I spent a LOT of time looking). It also contains every word in the Wikipedia databases (pages-articles, retrieved 2010, all languages) as well as lots of books from Project Gutenberg. It also includes the passwords from some low-profile database breaches that were being sold in the underground years ago.
Best thing is, its free, although you can (and should!) make a donation!

Try the CrackLib dictionaries: https://web.archive.org/web/20161225012801/http://linux.maruhn.com/sec/cracklib-dicts.html

I tested the likelihood of collisions of different hashing functions. To help test, I tried hashing
With one list of English words you'll cover nearly everyone's password.

[Analysis] Dictionaries & Wordlists
In general, it's said that using a GOOD 'dictionary' or 'wordlist' (as far as I know, they're the same!) is 'key'. But what makes them GOOD? Most people will say 'the bigger, the better'; however, this isn't always the case.. (for the record this isn't my opinion on the matter - more on this later).

You'll find lots of words in lots of languages on the download page for the English Wiktionary. enwiktionary-latest-all-titles-in-ns0.gz contains just page titles, including phrases - it might have underscores instead of spaces though. (we have English definitions of words from many languages).
And of course there's also WordNet.
(sorry but as a newbie I can only include one link)

All the posts so far have great information, but remember you can always generate word lists yourself with a utility like crunch.
If you have an idea of what the password parameters are (for example, has to be 8-10 chars with only letters and numbers, no symbols), you can pipe crunch to most bruteforce programs with the tailored parameters.

This is one that I have found useful over the years:
It includes popular passwords, fuzzing based on attack type and popular user names.

Have you considered instrumenting OpenSSH to log password attempts. Its common to log thousands of attempts every day for an internet connected host. That will give you a list of several thousand common passwords that have some track record of success AND hint at users other than root which are common targets (e.g. nagios, db admins etc). Once you have a list then you can then use cewl to generate many more variations of these basic passwords.

I'd also recommend looking up lists of male/female names: a huge number of passwords are based on name. Again, once you have a basic list using cewl on it will generate many variations.
