That’s an interesting question, Danni! There have been a lot of discussions lately around signs and determining whether or not something carries deeper meaning or is just simply a natural occurrence.
I personally believe that the best teller for whether or not something has deeper meaning is how you feel about it. Trust that intuition of yours! If you’re still unsure, another clear way to determine is through repetition of the sign.
@Silverbear said it well in her discussion Is This a Sign?
It sounds to me like you feel that a higher power has been trying to reach out to you several times. If you’re still not clear about why they are doing so, I would say it’s a good idea to reach out to them (if you feel safe and comfortable doing so).
A good way to confirm signs is through Divination. Ask for clarity with tarot cards or perhaps consult spirits directly through a medium like a Ouija or Spirit Board.
If there is something important you need to know about, I am confident that whoever/whatever is reaching out to you will continue to do so until the message is received or is no longer relevant.
Good luck and blessed be, Danni!
