you talk about recieving a Christian Sacrament and using Native American Sacraments.
Exactly.
God will reveal Himself to you if you ask Him. He says "knock, and the door will be opened." We can pursue all sorts of spiritual pathways to attain enlightenment, while He is sitting right there waiting for us to just ask.
Let Him reveal.
Within most religions, including Christianity, there is recognition of spiritual entities that get involved in people's lives. We can rationalize all we want about how primitive it is to talk of supernatural beings, but there are millions of first-hand accounts across all cultures and eras.
You invited the supernatural. Now it seems you have the supernatural involved.

There is a chance that God was speaking to you in the vision, since you did this with the intent to reach Him. Pray about it, and allow Him to use all experiences for good.
Rejecting the sacrament could have been natural causes, but also seemed a signal to you that something is amiss. Make sure you deal with it now, because little intruders cause great damage over time.
This is going to be simpler than you'd expect. Jesus paid the price for our redemption. It is paid, it is done, no matter what choices you have made. Put your situation into His hands, and let Him work it out.
Jesus showed He had the authority to cast out demons, and asked His followers to do the same for others. That means you. If you even have the slightest inkling that a supernatural force (other than God) is hovering, then audibly tell it to leave. You have the right to do this, because He gave you this right.
Even if the vision was from God, it doesn't hurt to tell other forces to take off.
Make sure that guilt does not control your future. It is good to express remorse and repent. But the objective in repenting is moving on in freedom. That is God's desire for His people, to move in the freedom of forgiveness.
