I had strange things showing up while meditating

So... i turned 15 a few months ago and i discovered some youtube channels that spoke about spiritual ilumination and other stuff,i watched a lot finding myself relating to almost everything there and decided i should try because why not. One day i went to my bed and first i took 5 minutes of controled deep breathes and then closed my eyes and cleared my mind,at that moment i seen "something" from my back like my field of view got bigger. I had my eyes closed but i would still see the things behind me and my room,and all that with my ryes closed. I got scared as this was my very first time experiencing something like this so i opened my eyes. I tryed again after half and hour but i was not calm enough so i went to sleep. The very next day in the morning i went to my desk and had deep breathes again. 5 seconds in and 5 out. Then closed my eyes. After like 1 minute i got really calm but then i started seeing a red thing in front of me. Was looking like a tomato but not perfectly rounded and then my eyes started moving involuntary and then turned down. My 2 questions are : is all i went trough these 2 days good or bad? And why do my eyes move involuntary and turn down. Thanks.
