I woke up to a smell in my house, seems to be coming from the registers and it smells like something laying on a light bulb and burning. Can you help me??

First check to make sure the smell is from your furnace. If so it is a good possibility the smell is from the furnace blower motor. You might check that area of the furnace and also check to see if the furnace blower is working. If you are really concerned there could be a fire somewhere in your home call the local fire department. It is always better to be safe than sorry.
