Of course it's dangerous, and not what a beginner should be doing. You could end up summoning very bad or demonic spirits.
Please read the books I recommended to you before.
Start with inner witchcraft; it should help your psychic abilities too. Focus on meditation, holding intention in your mind, and basic cleansing exercises to clear you of any energy you might pick up while doing outer exercises.
If you are interested in working with spirits, maybe start by helping them. One of the first things I started doing was going with another witch to visit graveyards and do a blessing.

Thanks for the advice ghost wolf 04. I’m not really sure what kind of witch craft I’d like to practice but moon rituals and spells sound interesting.

Also what exactly is inner witch craft is it just meditation intention holding cleansing exercises or is it something else entirely.

Hello and merry meet Livingly, I am so sorry it took so long to respond to your questions but hope I can help. You can work magic by yourself or with a group, there is a ritual known as circle casting which is used to create a sacred circle around yourself or others if you are in a coven. A lot of covens will circle cast around the members and guest that may be attending the ceremony. An invoking Ritual is usually used to summon the Lord and Lady, the guardians of the 4 corners of Earth, Air, Fire, Water, and this can involve spiritual entities, dearly departed human family or a mixture of both depending on the season celebration, the coven or the solitary individual performing the ritual.

Wicca traditionally has 8 Sabbaths a year. These celebrations are approximately 45 days apart and centers around the 4 seasons of Spring, Summer, Fall and Winter and the midpoints between the seasons for a total of 8 holiday celebrations.

The Moon rituals you are asking about are called Esbats and a witch can hold a moon ritual for spell work, Invoking, Charging Energy, Celebrating or just plain meditation on any night or phase of the moon, but generally the 4 phases of the moon of New, 1st Quarter, Full, and Last Quarter are generally the most popular times a witch or Coven will work with Moon Magic.

Since I am more of an elemental Witch I seldom Invoke spirits because I want to have a private sacred space when practicing my witchcraft so you can open a circle without the use of any spirits at all!

Like Ghostwolf04 said working with spirits should be used with caution. If you do invoke spirits be sure to be specific of who it is your calling because if you are not specific. Evil entities have the right to come to you in addition to helpful loving spirits. One final thing to take note in working with spirits is that every time you invoke a spirit, your spiritual eyes will be open a little more and in time you will be able to detect the dearly departed around you. This is very appealing to spiritual entities and they will be attracted to you because you will be able to detect their presence. If you open a portal into their world, they have the right to open a portal to your world so you may have contacts with Ghosts at anytime of the day or night which can be very draining and scary at times if you are not used to spiritual contact!

As a Witch the sky is the limit, you can work with Spells, Divination Readings, Tarot Cards, Rune Readings, sharpen your Empathic abilities, Work with Healings, Clairvoyance, Invoking Rituals, Mediumship, Tele Kinetic work, Astral Projection, Perform High Ceremonial magic during Sabbaths/Esbats, Read Auras, perform Reiki work, make Potions *use caution!* Sage and cleanse yourself, people or objects, Channel Spirits *Caution Channeling can lead to possession if not properly trained to protect your self*! Charging energy, Candle Magic, and so much more!

Well I hope what is wrote is helpful to you, the last thing I can say about staying safe is to focus on yourself first before practicing magic. Learn to control your fears, your doubts, your anger, and understand who you are as a person. Have a good heart, be happy in your work, seek Perfect Love and Perfect Trust in everything you do and when you make mistakes laughter is a requirement because no one is perfect and when you make mistakes you become a better student in this Nobel way of life! :)
