I just played stockfish 5, which is supposed to be rated 2000 (so it should have beaten me easily). However, it made some weird blunders. I'm not saying I'm better than stockfish, (I'm not even close), but why did it make so many weird blunders?
Because stockfish 5 != 2000 rating on lichess.
I read that the way weaker versions of stockfish (elo on Lichess) are implemented is by "randomly" making some blunder.
It doesn't consistently play like a 2000, more like a 3000 on most turn and suddently random blunder.

True
Stockfish 5 does not play like a human at all, and it is even more true in pawn endgames where it makes horrible blunders (just trade pieces and go to the endgame to have a relatively easy win). Just like Stockfish 4, 3 etc. it can play incredible moves sometimes but then just make nonsensical terrible mistakes.
I'd say the computer starts to be more regular in its play style around Stockfish 6, as it mostly plays well all along. The endgame skills of SF6 remain doubtful, but one has to reach the endgame first :).
If you want a reliable sparring partner, play SF6, it plays pretty consistently well and usually does not make random atrocious blunders.
