Simulating the pressure of competing?

I have atrocious stage fright and often blank out what I should be dancing. I’m doing my best to practice not just until I know my steps but until I can’t forget them, and to work on reducing the amount of anxiety I have around competition. Long term the goal of course is to not find competitions so stressful (performances are fine), but while I work towards that, I think it would really help if I could practice being under pressure. Does anyone have tips for how to trick yourself into feeling like you’re dancing in a high-stakes scenario when you’re by yourself and the stakes are objectively very low?
