Totally normal, anxiety dreams.

First, you need to realize that our sleep cycles have 5 stages and last about 90 minutes and then repeat until we wake up in the morning. So, if you fall asleep at 10 pm, you will go through the 5 cycles of sleep every 90 minutes until you wake up in the morning.

Having those two anxiety nightmares so close together, means you had an anxiety nightmare twice in a row, during two back-to-back sleep cycles. Totally normal.

Previous nights of insomnia or sleep deprivation.

The only way to deal with the nightmares like the ones you've had back to back, is to see if you had any of the above triggers before that night of sleep occurred. Because one or more them, could be the cause.
