It's not ok to work out to the point of passing out, even if you are safe in terms of spotters, or whatever. The fact is, if the passing out is related to your lifting then you are lifting incorrectly. If its related to some other condition that is brought on whenever you lift, it's also not ok and you'd need to figure out why. at that point, yes, having a doctor check you out would be smart.
Anxiety and stress are bad things. They can do everything you mentioned, and everything you mention could be related to anxiety. I used to nearly pass out when I stood up and yawned or stretched to hard. Most people probably have. This wasn't anxiety related, but simply not getting oxygen to the head. Now, if I started panicking thinking it was something else, I might always have been stressed thinking I had some sort of medical condition rather than just a nothing that happens to everyone for good reason. The thing is, you could be in a loop of anxiety by stressing over things that are nothing which causes them to get worse, which causes you to stress about them more. Would you consider yourself hypochondriac when it comes to your health? A doctor might be quick to dismiss you for that reason alone - but at the same time, something could be wrong, so its not reassuring either way.
One thing for sure, its not normal, and to avoid working out hard because of those sympotms is only hiding the symptoms. Whether its as simple as bad form, bad breathing technique, anxiety related, or something serious, you shouldn't be experiencing them so best to try to get to the route of the problem.
