What if Phobias are based on how we died in our past life? Like lets say your afraid of heights. What if the reason your afraid of heights is because in your passed life you fell off something high and died? I don't know. Just some random thought I had..

i have Meglaphobia and Tripophobia so thats kinda weird

Explanation:

Interesting thought but flawed. Phobias are nature's way of keeping us alive. For example, some people are terrified of clowns. This is caused by a traumatic experience in the past like a movie, dream, or encounter. Most humans are naturally afraid of large bodies of water because of our lack of desire towards drowning and the possibility that there's something massive down there. Sometimes the human mind cannot understand things so it makes certain things up like sea serpents or the loch ness monster. While Nessy might be a prehistoric animal that got trapped when the water subsided or a piece of floating wood, we're both terrified and interested.
