Mediumship

I have started to meditate 2 years ago when I was going through a tough period in my life. From the very first times my head started to spin and I had no idea what that was. I then after reading a lot, realized this was the same way Esther Hicks first started to communicate with Abraham Hicks. My head make different symbols and I can communicate with my spirit guides and ask questions and receive answers. Some answers about myself and something deeply related to me usually are right, some other simple questions such as my brother's teacher name is incorrect. I also did healing sessions on my own body and then after I found out that is called Reiki, but I know I was guided by spirits.

I did a psychic blueprint and life past reading with a medium and I turned out to be clairvoyant 75 and Trace Mediumship 80 in a scale of 100, that was just when I was starting with meditation and so on. Now I have a way better understanding of chakras, energy healing and mediumship as I have been watching a lot of videos and reading books about it. The medium also said I am a very old soul and have been here since the first incarnations.

The other day I saw flashes of light after a healing session I did on myself and the lights in the house started to blink.

Also since I was young I realised that if I dream with water it takes about 1 month to receive some bad news about someone passing away. I also could see signs on the sky, almost if I could read what the clouds were saying in many forms.

After this development I have doing of reading and chakra clearing, I have realized that even the smallest movements around me I can notice, my perceptions have doubled or tripled I would say, probably because of my 3rd eye opening.

My questions are:

1--Am I a medium? I know everybody is to some certain degree but I would love to hear your comments

2--Why I am channeling symbols? Usually the Infinity, Caduceus, Spiral and some others which I cannot relate to yet...

3--Why some answers related to me seems true and others are incorrect? Am I somehow making up this on my mind?

4--When I ask the name of the spirits guides that are with me I get an answer, how do I know these answers and the others I receive are true or not? I have received once as Abraham Hicks. Is that because I follow them or how do I know I really channeled them?

I know I must develop the sense of trusting the answers but in the beginning it's hard as I am not experienced with that, specially when some answers are not correct. I know it will come with time but I would love to hear your comments and experiences.

Thank you so much, love and light.
