Why did I feel weird after alcohol, was my drink spiked?

I was out a few weeks ago with a friend at a city bar, I had a cocktail and only two second drink of the night but all of a sudden I felt very weird. I’ve never felt like it, very hard to describe like out of it, nauseous, dizzy, fast heart beat. It doesn’t sound like the normal spiked reaction with passing out etc but still I wonder, I never left my drink out my sight but it was odd, unless it was an reaction to something?
