It is a psychologically valid observation, heightened emotions and stressful situations can cause a person to ascribe simple random events as being a sign from God. Certainly these may make you wonder, but Godly wisdom would cause you to carefully evaluate your choices and decisions, rather than make a decision based on what you may think is a sign from God. Instead of throwing caution to the wind, it is wise to always consider whether your choices and decisions are in harmony with God's Word, Will and Purpose!
