When it comes to people's experience of the good spirit world and Jesus there is obviously a lot of those taking part. A compilation of some of these have been made by Dr Gunnar Hillerdal in the book "They saw and heard Jesus." The book is out of print but can interlibrary loan by libraries or purchased through Bokbörsen: http://www.bokborsen.se/
These different personal experiences is really a challenge to take part. You are not convinced yet, you have everything to gain to form your own opinion by, for example, learn from other people's experience. Simply having a dismissive attitude is unfair and simplified approach to what people at all times have been a testimony of.
There is a great spiritual quest of our time and it is important to find the bright and good way.
