Insomnias

Its 10:23. I'm laying on my bed awake. When I close my eyes, I feel like someone or something is opening it. I hate insomnias. What might have caused it? I've been on my bed for 2 hours and yet I don't feel tired. I put on nice relaxing music and put some lavender lotion and yet none works. I stayed up reading a thick book and my eyes don't feel heavy at all. I can do a good job sleeping through Social Studies and Math but just not on my bed.
