Sharon   Thank you for your question and welcome to AnxietyConnection.com. I am not a medical professional and would not be able to give you medical advice.   You don't mention whether you have been diagnosed with anxiety and if this is ongoing or if this just began recently. Some people with anxiety do have anxiety attacks while sleeping or have difficulties with early morning anxiety.   Tips for Coping with Early Morning Anxiety   Morning Anxiety   As far as palpitations, these are frequently not dangerous but if you have not done so, I would suggest speaking with your doctor to rule out any physical cause for the increased heart rate.   Heart Palpitations and Anxiety Attacks: Should You Be Worried?   How to Manage Palpitations   I hope this helps   Eileen
