When one or more people come into or out of your timeline on earth:

It creates a time wave or Time Shock that everyone experiences to a greater or lesser degree but might not know what it is they are experiencing. The closer to you that this person is (like a friend or relative) the harder this is going to be to try to survive this time wave or time shock).

This is why I say it is important (especially in cities and communities) to be in the moment in your decision making so you can survive them when they occur.

What is strange is that vehicles often know when time shocks or time waves are going to occur (don't ask me why) but you can ask them if they are going to crash. So, if you can hear what they are telling you, you will know what planes or cars or trucks not to get on (even if you are driving them). What I usually do when something like this is coming is I just wait about 5 or 10 minutes before driving one of our cars or truck. This is how I deal with this. But, if  plane says: "I'm going to crash to you!" I really advise you not to get on board because they will tell you the truth usually sort of like angels do about the future. I understand how angels know the future which is that they don't live in time and space and so can visit any time past, present or future that they are allowed to. So, if an angel tells you something it is really important to listen because often it is life or death what they are telling you.

By God's Grace

Note: At this point literally thousands of people (from this time line) aliens (from other timelines and planets) are entering this time daily (or leaving this timeline). So, as they do this it creates shocks to the lives of everyone on earth and sometimes people die in cars, trucks, buses or trains or planes directly because of these "Time Shocks" or "Time Waves". and this happens NOW every day (at least thousands of people and beings are entering or leaving our timeline daily. Sometimes on rare occasions it is up to 100,000 beings are coming or going at the same time. By the way this really affects the weather too and is one of the causes of what we call Global Climate change.

One of the reasons I can get away with telling you all this is I have no technical evidence that could get me killed for knowing these things. But, if you are intuitive like me you likely sense most of this anyway yourselves and wondered what it was that you were experiencing.

Just imagine a Men in Black movie Scenario. This is closer to the truth than you know.

question: Are people primarily going into the future or the past?

I'm not sure about this question. However, I do know that it is possible through time travel also to go directly to other planets or dimensions with this type of technology sort of like how they do it in

So, for example people could evacuate the planet before something bad happened using these kinds of technologies or at least have enough settlers on other worlds so if anything bad happened here that there would be some from earth that survived. Most advanced technologies 1st world governments aren't talking about because it would collapse all governments and religions if they did here on earth.
