This Feeling?

I'm fairly new to experiencing these kind of feelings, and it's only really been happening in the last year. My first proper experience of anything "different" was last year. My mum was suffering with later stages Dementia and had been admitted to hospital with a UTI/Pneumonia. She was in there for 5.5 weeks in total before she passed away. I had a really dark, dreaded and nasty feeling hit me about 2 weeks before my mum passed, so much so my husband noticed something wasn't right with me. It was a horrible feeling. The day my mum passed I had awoken at 2 am and could't settle back to sleep for a good hour or so (not like me, I love my bed/sleep!). I then received a call from the hospital asking me to attend my mums side at 4.25 am. It later transpired my mum nearly asphyxiated at 2 am. I knew she was leaving us, I just knew.

Since my mums passing, I regularly get visions out of the corners of my eyes. They're like balls of masses. Black with a white fluffy outer circle? But when I turn to see it, it goes. Is this a spirit or a guardian angel, or even my mum or dad?

Lately (since about November 2013), I have been getting another gut feeling. It's very much like an adrenalin rush, or a huge sense of elation, almost like something or a weight has been lifted. It'll probably last for about a minute or two, and will then fade away. Maybe like a feeling of winning the lottery would bring! Its been coming and going at various times and days.

There is a psychic ability that runs in the family, but most of my aunties do not talk about it or will not advise me on what I am experiencing or what I can do to develop myself.

Can anyone point me in the right direction here? What are my next steps? Who do I speak with? I have been told I need to cleanse or ground myself. How can I do this? Any advice is greatly appreciated! Thank you all in advance.
