Does anyone else experience this: laying in bed at night, on the verge of falling asleep, and all of a sudden it feels like your heart skips a beat and is going to come out of your chest &amp;? Like scares the crap out of you when it happens?

I’m 99.9% sure this is the result of my anxiety, but I’m interested to hear if others have experienced this and if there’s any tactics to control? 

Last night this happened to me about every 5 minutes throughout the night and drove me to the point of a breakdown today.
