Is it normal to make numerous errors in my speech?

I have a history of making malapropisms and grammatical errors like crazy (mostly when talking) and it's starting to creep me out, like there's something wrong with me. Earlier today, I made the mistake of saying that my grandmother "Judges a man not by the color of his contents, but by the skin of his wallets," that I had "run off" of water instead of run out, I've been making a lot of unintentional neologisms, and I constantly have to start my sentences over again because I keep forgetting where I'm going with them (or they go off into completely unrelated territory). This has been getting especially more frequent lately and I'm wondering if it's normal.
