Maybe: If you are shy or anxious , sometimes it is difficult to find the right words to say. Or if you are thinking about so many things at once, or doing too many things at once, e.g. Watching t.V., listening to music, on the computer and texting your friends while you are studying your mind might go blank. However you might be having a neurological problem like a petit mal seizure. If new sx go to doc.
