Ah. Well, first of all, understand that you are in God’s hands, and nothing will happen to you that is outside of His control. If you die, you will go to Him for judgement, and He will cause you to go where ever you were always going to choose to go. You cannot go to Hell by accident, and you cannot go to Heaven under your own power.
Second, it seems as though God is using this circumstance in your life to call you back to the Church. What you need to do is get back into the RCIA process, complete it (take as long as it takes - the more you try to rush, the more obstacles will be thrown into your path, until you learn patience, and how to persevere).
I first got the Call when we lived in Iran; it was during the Revolution. I had just had a baby and had nearly died in childbirth so my own mortality had just smacked me in the face. We were under martial law and curfew; there were armed soldiers stationed at all the intersections of the city and they held their weapons at ready. Large intersections got tanks and APC’s in addition to more troops. Helicopter gunships patrolled over the city regularly. Being very obviously Western, I felt like I had a target painted on me every time I left the house, what with the mobs shouting ‘Death to America’ and all. I did get rocks thrown at me. God lit the fire in me to be baptised and I was afraid that I would die before it could happen.
However, when I presented myself, I discovered that it wasn’t as easy as all that. Due to various circumstances, it took nearly 2 years from when I asked to when I finally received Baptism and Confirmation and it was definitely worth the wait even though I was sorely tried during that period.
There is a great deal to learn, especially if you know little about the Church and the Faith, or if, in fact, you have been stuffed with misinformation about the Church, a lot to ‘unlearn’. It is not something done lightly, or even just because you are going to be travelling by air in the next couple months. I do not think any priest will consider that to be a grave enough reason.
Being Baptised is not an end, it is a beginning, the beginning of your new life in Christ. Much like a wedding is the beginning of a marriage. It is not a once done, now I can go back to the way I used to live event. It is not a magical heaven insurance policy.
What jmcrae is describing is what is known as the Baptism of Desire. Should you die in the process of your formation, your sincere desire to be baptised is duly noted by God and you can trust in God’s mercy for He will recognise your desire to be joined with Him.
From EWTN:
WHAT IS BAPTISM OF DESIRE? Baptism of desire is the implicit desire for baptism of water by a person who makes an act of perfect love of God, based on faith and with a sincere sorrow for one’s sins.

As far as the strange phenomena (also experienced and still do from time to time but that’s another story), you can have your house blessed by a priest. Get yourself some holy water and use it often. (it is free. Bring a small bottle to the church and take some. ask the priest if you feel uncomfortable about it or if the large container is not accessible) Cross yourself with it frequently in the Name of the Father and of the Son and of the Holy Spirit.
May God bless you on your journey home.
