found my old steam account - strange things happened there lol

You are the chosen one.

Somebody got hold of it. Been using it for 3-4 years. You found it again. Change password. Profit.

You don't have these games in your account. They are just installed. You can't start them with your old account.

so that's the explanation:

1. some guess ur password or something ?
2. login to ur account
3. make it their primary account
4. buy games for ur old account
5. want to change the password

strangest thing is i'm not sure

You have a secret twin, better stay alert.

That's better than even SteamGifts! xD

strange, free games LOL.

Noobs, noobs everywhere...

Sigh... Nobody stole your account or whatever. This is what you get if you log in with different accounts on the same PC. Games will appear in the other account too, but they won't be playable.

The request for new pass might be because some of your friends (like my cousin) knows my acc pass and nick :D but he doesnt know my email pass so he was attempting once to enter in my acc and I was getting in my mail lots of forgotten password and new pc mails and I was like "WTF!?what is going on!??!" but I he told me that it was him xD

Gaben gives out free accounts from time to time. BTW why did you create that account without using it?

it may be that someone used a used key and clicked remind my password

nothing to say except lol

Stored content from certain games will show up in any account that you log into on that PC. If you log into that account from a different PC, you'll see how empty it really is lol.
